GLOSSARY OF TERMSAir WindowA device that blows purge air out of the transceiver and retroreflector module into the stack, pre-venting the stack gasses from entering the modules. This maintains a clean space between themodule optics and flue gasses, preventing particulate buildup on the optics. The air window con-tains a manually sliding seal that is used to isolate the module from the stack when purge airmust be turned off. The air window also contains a ball joint used to align the optics.

Corner CubeA device used by the OPM 2001 as a retroreflector. Corner cubes come in different sizes basedon the path length between the transceiver and retroreflector modules.

EPAEnvironmental Protection Agency.

ExtinctionSee optical density.

FSK (Frequency Shift Keying)The sumperimposing of a high frequency digital communication signal on an electrical signal. TheHART communication protocol uses FSK to communicate between the hand held unit and theintelligent electronics over the 4-20 mA analog output line. The HART signal does not affect the4-20 mA analog output, since no energy is added to or removed from the loop.

HART CommunicatorA hand-held communications and interface device that can communicate with HART compatibleinstrumentation. The HART communicator can be used to view data and configure and calibratethe OPM 2001. The HART communicator uses the frequency shift keying technique to communi-cate to other HART compatible device over the 4-20 mA analog output line.

In SituThe measuring of the parameters of a process without extracting the sample from the processstream.

LCW (Liquid Crystal Window)A solid state device that changes from translucent, scattering and diffusing light, to transparentwhen an electrical signal is applied. This allows the OPM 2001 to control the path of light throughthe transceiver module with no moving parts.

lfThe flange to flange distance between the transceiver and retroreflector modules when installedon the stack.

ltThe inside stack diameter at the transmitter location.

lxThe inside stack diameter at the stack exit.

lx/ltThe ratio between the inside diameter of the stack at the stack exit and at the transmitter location.This value is used to correct the transmitter reading to calculate stack exit opacity.

Neutral Density FilterAn optical filter used to reduce the intensity of light without changing its color.

OpacityThe amount of light being scattered or absorbed by particles in the path of a beam of light.

Optical Density (OD)The degree of translucence of an optical medium. Optical density is expressed as:OD = -log(transmittance/100). An optical density of 1 is equivalent to a 10% transmittance, or anopacity of 90%. Also called Extinction.

Photopic RegionThat region of the light spectrum visible to the human eye.

Purge AirFiltered air provided by the purge air blowers. Purge air is used by the air windows to prevent thebuild-up of particulate on the module optics.

RetroreflectorA device that reflects light in such a way that its angle is parallel to the incoming, or incident, rays.The OPM 2001 uses a corner cube in the retroreflector module to reflect the light beam from thetransceiver module back to the transceiver module.

Ringelmann ScaleA scale ranging from 0 to 5 used by observers to rate the opacity of stack emissions. Each num-ber on the scale equals approximately 20% opacity, i.e. a Ringelmann number of 2 equals 40%opacity. The Ringelmann scale is very subjective, as it can be influenced by sky haze, the posi-tion of the sun, or interpretation of the observer.

TransmissometerAn instrument that uses opacity to measure the particulate level of stack emissions. Sometimesreferred to as a dust density transmitter.

TransmittanceThe complimentary function of opacity. Percent opacity plus Percent transmittance always equals100%.

Zero JigA device used to provide a zero opacity reference for the OPM 2001 without the need to removethe transceiver module from the stack. Also holds neutral density filters for performing spanchecks.

1-1 COMPONENT CHECKLIST OF TYPICALSYSTEM (PACKAGE CONTENTS)

A typical Rosemount Model OPM 2001 Trans-missometer Opacity/Dust Density Transmittershould contain the items shown in Figure 1-1.

1-2 SYSTEM OVERVIEW

a. Scope

This instruction bulletin is designed to sup-ply details needed to install, operate, andmaintain an OPM 2001.

b. Reason for Measuring Opacity

Opacity refers to the amount of light beingscattered or absorbed by particles in thelight beam path. An opacity or dust densitytransmitter (also called a transmissometer)measures the particulate level of stackemissions. One of the most common rea-sons for measuring opacity is to comply withEnvironmental Protection Agency (EPA) orother national requirements. Federal regu-lations for new emission sources and manystate regulations for both new and existingsources specify maximum limits for stackemission opacity.

A transmissometer can be used in a varietyof applications. Those applications includemonitoring the efficiency of emission controlsystems, detecting broken bags in bag-houses, and determining the time rappingcycles for electrostatic precipitators. Anotherapplication is to gauge the effectiveness ofinjecting flue gas conditioning agents usedto improve electrostatic precipitator per-formance.

Opacity data can also serve as a rough in-dicator of combustion efficiency. Extremechanges in opacity may indicate inefficientcombustion or boiler problems. Because the

transmitter gives accurate, immediate-response data, corrective actions can betaken as soon as problems occur. This dataserves not only the compliance requirementof pollution regulation standards but also asa means to achieve improved efficiency andoperating profit.

Originally, a trained smoke reader deter-mined the particulate level of stack emis-sions solely by observation. The opacity ofthe plume was judged in reference to astandard Ringelmann scale of 0 to 5. Thesedeterminations tended to be influenced byseveral sources of error such as sky haze,sun position, and the subjective determina-tion of the observer. These sources of error,especially at lower opacity levels, can pro-duce highly variable readings even whenperformed by a trained observer.

c. System Description

The OPM 2001 is an in situ optical trans-mitter that uses a visible light beam in thephotopic region (peak and mean responsesin the 500 to 600 nm range) to measureopacity in stack emissions. The OPM 2001contains no moving parts except for blowermotors, which eliminates sources of wearand possible failure.

Federal regulations and many state and lo-cal laws use visual observation as a refer-ence. Thus, for a true correlation, it isimportant that transmissometers use thesame spectral response range as the hu-man eye. This portion of the spectrum iscalled the photopic response range. Sincevisual readings are taken at the stack exit,the OPM 2001 compensates for the differ-ence between stack diameter at the exit andstack diameter at the installation site.

The OPM 2001 consists of a transmitter/receiver (transceiver) module, a retrore-flector module, and intelligent electronics.

The transceiver and retroreflector mod-ules are mounted directly opposite ofeach other on the stack (Figure 1-2). Thetransceiver projects a controlled beam oflight across the stack. The corner cubebounces the light back along a parallelpath to the transceiver. Particles in thegas stream cause a certain amount of thelight to be scattered and absorbed. Thisamount varies depending on the particu-late content of the gas stream and theparticle type and size.

The light then strikes a detector, which con-verts the light into a voltage that can be

processed. The detector signal is amplifiedby an independently powered detector/amplifier board. The amplified signal is thendigitized and transmitted to the intelligentelectronics. The intelligent electronics cal-culates opacity, sends commands to thetransceiver, and provides an operator in-terface via HART communications.

Because the beam passes through thestack twice (once in each direction), the re-sulting value is a double-pass transmittancemeasurement. By passing through thesmoke twice, sensitivity to low opacity levelsis increased.

The measurement value is compared to areference value previously determined withno smoke in the light path. The resulting ra-tio is the transmittance value for the meas-urement path. This ratio can then beconverted to units of optical density, stackexit opacity, and dust concentration.

The reference value depends on the lf di-mension shown in Figure 1-3. Also illus-trated are dimensions lx and lt, which arenecessary for OPM 2001 calibration andsetup. These dimensions are defined asfollows:

lx = inside stack diameter at stack exit.lt = inside stack diameter at the trans-

mitter location.lf = flange to flange distance between

the transceiver and retroreflectorunit. It is also the distance that mustbe used to calibrate the unit offline.

The LX/LT parameter is entered in theBASIC SETUP submenu of the HARTCommunicator. See paragraph 3-8c formore information.

Opacity is a complementary function oftransmittance. It is a measurement of theamount of light that is blocked or absorbedby the flue gases. The measurement of

Figure 1-3. Calibration Dimensions

smoke opacity is sometimes referred to inRingelmann numbers. By definition, Ringel-mann No. 1 is equivalent to 20% opacity withthe opacity increasing 20% for each subse-quent number. This scale is based on asingle-pass value as would be read by a hu-man observer.

The relationship between opacity, transmit-tance, and optical density (or extinction) isshown graphically in Figure 1-4 and in thetable in Appendix A. One hundred percenttransmittance is equivalent to 0% opacity orzero optical density. Opacity and opticaldensity are logarithmically related in such away that zero optical density equals zeroopacity; an optical density of one is equal to90% opacity; an optical density of two isequal to 99% opacity, etc.

Model OPM 2001

The OPM 2001 automatically compensatesfor the effects of ambient light, zero drift,and component aging with every measure-ment cycle. Four separate voltages pro-duced in each measurement cycle arecompared against two sets of referencevoltages taken either off stack or in a clearstack. The first set is taken in 0% opacityconditions, and the second set is taken insimulated 100% opacity conditions. The re-sulting reference zero and span voltagesproduce a reference point by which thetransmitter judges current operation.

d. System Considerations

All procedures in this manual must be per-formed carefully in order to gain the maxi-mum benefit from the OPM 2001. Propermaintenance is important for maintainingsignal accuracy and will greatly increase in-strument life.

e. Dust Concentration Measurements

The OPM 2001 uses an optical technique tomeasure opacity and extinction. Equatingthis to a dust concentration measurementrequires additional iso-kinetic sampling inorder to calibrate the unit. Iso-kinetic sam-pling involves taking a series of actual dustconcentration measurements in the flue andcomparing these with the extinction readingfrom the OPM 2001. From this comparison,a graph can be plotted (Figure 1-5) thatshows the relationship between extinctionand dust measurement exclusive to thatparticular application. This method takesinto account the variation in dust sizes anddensities in different applications. The pro-cedure is described in the followingstandards:

1. ISO 9096 Stationary Source Emis-sions. Determination of mass

concentration and mass flow rate ofparticulate matter in gas-carrying ducts- manual gravimetric method.

2. ISO/DIS 10155 Stationary SourceEmissions. Automated monitoring ofmass concentration of particles - per-formance characteristics, test methods,and specifications.

Figure 1-5. Example Relationship of Extinctionand Dust Concentration



Model OPM 2001

1-3 METHOD OF MEASUREMENT

The following sequence of steps determines therelationship of dust concentration to extinctionreadings:

a. After the OPM 2001 has been installed andis functioning properly, a series of gra-vimetric measurements are taken using astandard method as outlined in ISO 9096.As each measurement is taken, theequivalent extinction reading on the OPM2001 is recorded.

b. The recorded data is plotted and presentedin accordance with methods outlined in ISO10155 or a relevant local standard. This in-formation is used to calculate the extinctioncoefficient that determines the relationshipbetween extinction and dust concentrationmeasurement.

c. A typical graph and dust concentration cal-culation (Figure 1-5) shows a linear

relationship between extinction and dustconcentration. The calibration curve can belinearized and represented by the followingequation:

DC = kE + c

Where:DC = dust concentrationk = slope of dust concentration by ex-

tinction (determined from stack dustsampling test data)

c = y intercept of dust concentration(determined from stack dust sam-pling test data)

E = Extinction (measured variable byOPM 2001)

The values for k and c are then entered inthe DUST SETUP submenu of the HARTCommunicator to calculate the dust con-centration (DC) from the extinction value.Refer to paragraph 3-9e for moreinformation.

1-5 SYSTEM STARTUP PROCEDURE

Use the following steps to start the OPM 2001.If the opacity transmitter is installed to meet therequirements of EPA regulation 40 CFR, Part60, Appendix B, Specification 1, follow this pro-cedure prior to installing the opacity transmitteron the stack (see 40 CFR, Part 60, Appendix B,Specification 1, Section 7, PERFORMANCESPECIFICATION VERIFICATION PROCE-DURE). It is also recommended that certainparts of these startup procedures be repeatedonce the unit is mounted on the stack or duct.

a. Turn on power to the transceiver and retro-reflector modules immediately after their in-stallation to the stack or duct. Refer toSection 2 for the complete installation pro-cedure. Turn on the purge air blowers toensure that both the transceiver windowand retroreflector corner cube will be keptdirt free.

b. Turn on the power source to the intelligentelectronics and connect the HART Commu-nicator per paragraph 3-2. Turn on theHART Communicator and select CHECKOPTICS from the DIAG/SERVICE menu.Next, select the VSTACK menu option to placethe OPM 2001 in the check optics mode.

c. Align the transceiver and retroreflector.(Refer to Section 4 for the complete proce-dure.) If the alignment is performed off ofthe stack prior to the installation to meet theprior to installation requirements of 40CFR, Part 60, Appendix B, Specification 1,be sure the transceiver and retroreflectormodules are spaced within 1/4 in. (6.35mm) of the actual installed flange-to-flangedistance. Exit the CHECK OPTICS proce-dure when alignment is complete.

d. Set up the operating parameters in theBASIC SETUP and DETAILED SETUPmenus of the HART Communicator. Referto paragraphs 3-8 and 3-9 for the completesetup procedures.

e. Enter the PROCESS VARIABLES menuand select FLD DEVICE VOLTS per para-graph 3-6a. Four voltages are listed: VSTACK(stack), VLAMP (lamp), VAMB (ambient), andVDARK (dark). Selecting STACK TEMPERA-TURE displays VAD590 (ambient voltage)and TEMP (transceiver electronics tem-perature). These voltages and temperaturereadings indicate the up-to-date levels ofthese measured variables. If the stack orduct is clear of opacity, the stack voltagewill typically be set at 2.0 volts by the fac-tory. The lamp voltage will typically be set at4.0 V.

NOTEThe actual ambient conditions at theinstallation site may not be the sameas the factory conditions at the time oftesting. Therefore, some variations inthese two voltages will be observedbut will not affect the operation of theopacity transmitter.

f. View the opacity reading on the HARTCommunicator display online menu. Ensurethe primary variable (PV) or the secondaryvariable (SV) is set to display opacity. Referto paragraph 3-6b. Under clear stack condi-tions, or with zero jig installed, the opacityshould now read 0.0%. If the opacity read-ing is other than 0.0 ±0.5%, recalibrate theopacity transmitter.

g. Perform an offline calibration per paragraph3-7b. Reference voltages from the last off-line calibration are stored in the REF.VOLTAGES submenu in the DIAG/SERVICE menu. This stored data should berecorded and saved for later referencebefore proceeding with another offlinecalibration.

SECTION 2INSTALLATION

Before starting to install this equip-ment, read the Safety instructions forthe wiring and installation of this ap-paratus at the front of this InstructionBulletin. Failure to follow the safetyinstructions could result in seriousinjury or death.

2-1 GENERALProper functioning of the Rosemount OPM 2001Opacity/Dust Density Transmitter depends onproper installation. All procedures in this sectionmust be followed carefully.

2-2 CHOOSING A LOCATIONThe location of the OPM 2001 is important forobtaining maximum accuracy in the reading ofthe stack particulates. Keep in mind both clear-ance and process/regulatory considerationswhen choosing an installation location.

a. Clearance Considerations 1. Ensure the location is accessible and

provides adequate clearance to serviceand maintain the transmitter.

2. Allow 32 in. (813 mm) for clearance oneach side of the stack to remove andinstall the weather housings (Figure2-1).

3. Locate the transmitter no further thanone mile (1.5 km) from the intelligentelectronics.

b. Regulatory/Process Considerations

The EPA has established the followingguidelines for choosing an opacity/dustdensity transmitter installation site:

1. Locate the transmitter across a sectionof a duct or stack that will provide aparticulate matter flow through the pathof the transmitter beam representativeof the duct or stack flow.

2. Ensure the transmitter location is down-stream from all particulate controlequipment.

3. Locate the transmitter as far frombends and obstructions as practical.

4. If a transmitter is to be located lessthan 4 duct diameters downstreamfrom a bend, install the transmitter inthe plane defined by the bend. SeeFigure 2-2.

Figure 2-2. Transmitter Location

5. Ideally, locate the transmitter eight toten stack diameters upstream from thestack exit and three to five diametersdownstream from any bends, junctions,or other constrictions in the stack orduct.

For best results, mount the transceiverand retroreflector modules so the lightbeam is exactly perpendicular to thestack or duct and the beam goesthrough the center. Do not install thetransmitter downstream of a wetscrubber. The water droplets intro-duced to the gas stream by suchequipment will interfere with the opacityreadings. For an accurate measure-ment under these conditions, choose alocation upstream from a wet scrubberor a location downstream from thescrubber where the water droplets arevaporized by the reheating of the gas.

2-3 CALIBRATION

The OPM 2001 is factory calibrated for theflange-to-flange distance (lf) (Figure 1-3) of theinstallation site. If the unit needs to be recali-brated, refer to paragraph 3-7b. If a Dust Con-centration (DC) output is required afterinstallation, it is necessary to perform iso-kineticsampling on the flue gas while simultaneouslymeasuring the extinction (E) value. Refer toparagraph 1-3 for a description of thisprocedure.

2-4 MOUNTING FLANGES TO STACK

a. Form two mounting holes in the stack atlocations specified in paragraph 2-2. Holesmust be on the same horizontal and verti-cal axes. A liquid level can be used to en-sure that modules are installed on samehorizontal plane.

b. Install 6 in. pipe and 6 in., 150 lb flangesfollowing the notes in Figure 2-3. Pipemust be horizontal and should protrude atleast 4 to 6 in. (102 to 153 mm).

2-7 MONITORING OPACITY IN HIGHTEMPERATURE APPLICATIONS

a. Introduction

Measuring opacity in high temperature ap-plications such as incinerators can be det-rimental to the physical well-being of opacitytransmitters. Flue gases from incineratorsapproach 2000°F (1093°C). Opacity trans-mitters have reportedly melted at thesehigh temperatures.

Other less severe temperatures just over400°F (204°C) can also cause opacitytransmitter operation problems. In theseapplications, the opacity transmitter ismounted to a steel duct or steel stack. Ra-diant heat from the duct or stack can causethe temperature within the transceiver andretroreflector modules to exceed ambienttemperature limits.

b. Solution

The heat at the opacity transmitter must bereduced to permit accurate opacity moni-toring in these applications. RosemountAnalytical offers several solutions to helpwith these applications.

1. Thermo Isolators. Thermo isolatorsshould be used whenever the stacktemperature is above 600°F (316°C):for example, incinerator and hot steelstack applications. They provide aheat-resistant barrier between thestack and opacity transmitter flanges.Thermo isolators are a must with thehigher temperature incinerators.



Model OPM 2001

Rosemount Analytical offers thermoisolators for the OPM 2001s 6 in.mounting flanges. This 1 in. (25.4 mm)thick high-temperature gasket providessufficient thermo isolation to withstandhot face temperatures of 1700° to1800°F (927° to 982°C). Two thermoisolators are required for each OPM2001. Remember to add 2 in. (51 mm)to the flange-to-flange dimension (lf)when thermo isolators are used.

In addition, insulation and a cooling fin(Figure 2-7) can be installed betweenthe duct and the opacity transmitter to

ward off radiant heat. This barrier isrecommended for high radiant heatapplications as found in incineratorsand hot steel stacks.

2. Purge Air. A duct or stack maximumpressure is limited to plus 10 in. WC inorder to supply a minimum flow of40 SCFM purge air. These constraintsmust also be adhered to for this appli-cation to be successful. A flow of coolpurge air must be maintained or theopacity transmitter may suffer heatdamage.

2-8 MONITORING OPACITY ATLOW AMBIENT TEMPERATURES

a. Introduction

Measuring opacity in locations where ambi-ent temperatures can be expected to gobelow -20°F (-28.9°C) can cause falsereadings as a result of the extremely coldambient air being used by the purge airblowers. When extremely cold purge airmixes with the hot process gases, foggingcan occur. This phenomenon takes place atthe outlet of the purge air window assemblyand directly in the path of the opacity meas-urement. As a result, the opacity reading isfalsely represented as a higher than ex-pected value due to the presence of the fog.

b. Solution

The OPM 2001 can be ordered and/or fieldretrofitted with purge air heaters. Thisheater mounts between the blower and thepurge air window assembly in place of thecheck valve and elevates the temperatureof the purge air to prevent fogging. Refer toFigure 2-8.

2-9 SYSTEM WIRING INSTALLATION

a. Wiring Practices

The wire selected for supplying power to theintelligent electronics and modules must besized to meet the current carrying require-ments (capacity) for the application. Referto the specifications in paragraph 1-4. TheNational Electrical Code contains tables thatmay be used as a guide. Voltage classifica-tion must be equal to or exceed the ratedcircuitry voltage.

All customer-supplied wiring must conformto standard wiring practices in accordancewith local code. The wire must be able towithstand the physical stresses to which itmay be subjected during installation.

NOTEIf wiring an OPM 2001 with a generalpurpose intelligent electronics, refer toFigure 2-9. If wiring an OPM 2001 witha Type 4X intelligent electronics, referto Figure 2-10.

SECTION 3OPERATION

3-1 OVERVIEW

The HART Communicator is a hand-held com-munications interface device. It provides the op-erator interface to the OPM 2001. Its 8 line x 21character liquid crystal display (LCD) and 25keys are used to view data and to configure andcalibrate the unit. A pocket-sized manual is alsoincluded with the HART Communicator that de-tails the specific functions of all the keys.

The HART Communicator accomplishes its taskusing a frequency shift keying (FSK) technique.With the use of FSK, high-frequency digitalcommunication signals are superimposed onthe 4-20 mA transmitter current loop. The com-municator does not disturb the 4-20 mA signalssince no net energy is added to the loop.

To interface with the OPM 2001, the HARTCommunicator requires a termination pointalong the 4-20 mA current loop and a minimumload resistance of 250 ohms between the com-municator and the power supply. To simplify theconnection procedure, the OPM 2001 providestwo banana jacks at each of the transceiver andintelligent electronics sites so the HART Com-municator can be used at either location asshown in Figure 3-1.

3-2 HART COMMUNICATOR SIGNAL LINECONNECTIONS

There are two methods of connecting the HARTCommunicator to the signal line. For applica-tions in which the signal line has a load resis-tance of 250 ohms or more, refer to method 1.For applications in which signal line load resis-tance is less than 250 ohms, refer to method 2.

a. Method 1, for Load Resistance≥≥≥≥ 250 Ohms

Explosions can result in death or seri-ous injury. Do not make connectionsto the HART Communicators serialport, 4-20 mA signal line, or NiCad re-charger jack in an explosive atmos-phere.

1. If attaching the HART Communicator toan OPM 2001 using the banana jacksprovided at the stack termination boardor the intelligent electronics, refer toFigure 3-1 and the following procedure.

(a) Connect the supplied lead set tothe loop connectors on the HARTCommunicator top panel.

(b) Connect the opposite end of thelead set to the banana jacks oneither the intelligent electronics orthe stack termination board.

2. If attaching the HART Communicator toan OPM 2001 using a wiring termina-tion point in the analog output (AO1)4-20 mA signal line, refer to Figure 3-2and the following procedure:

(a) Connect the supplied lead set tothe loop connectors on the HARTCommunicator top panel.

(b) Using the banana clips suppliedwith the lead set, connect theHART Communicator in parallel tothe load resistance.
