1. Introduction
The Logika Technologies Two-Color Handheld Pyrometer, Model PMP-716, is primarily used in
the metallurgical industry to measure the temperature of high speed wire rod, hot rolled steel,
molten metal and slabs/billets. Pyrometers are able to “look” into a process and measure the
target temperature from a distance, thus providing an accurate reading while eliminating
problems associated with contact measurements. Dual wavelength Infrared pyrometers are
able to overcome application challenges such as targets with a small cross-section, variable
emissivity, dust, water or other interfering media between the target and the pyrometer.
Accurate temperatures can be obtained even when the target is 90% obstructed.
The PMP-716 uses a visible laser to assist in aiming and a microprocessor to set up parameters
like emissivity, slope, response time, sampling mode etc. It also has an interior ambient
temperature compensation unit, which allows the instrument to work in temperatures of
0~50°C (32~122°F).
PM-716 is operated by a 9V 6LR61 battery. It also has real time data storage capacity which
can save up to 1000 data points.
2. Description
2.1 Operating Principle
This two-color (colorimetric) infrared pyrometer senses two adjacent infrared wavelengths
emitted by the target using a laminated photosensitive detector. By measuring the infrared
energy emitted from the target, the pyrometer calculates the ratio of these wavelengths to
determine the target temperature.
The primary advantage of Logika’s Two-Color Infrared Pyrometer over thermocouple
temperature measurements is that the pyrometer directly and instantaneously measures the
target temperature rather than inferring it based on the temperature of the atmosphere
surrounding the target.
The advantages of the Logika PMP716 two-color pyrometer vs. a single color pyrometer include:
• Overcomes optical fouling or interfering media between the target and the detector,
such as dust, dirt, smoke, and water vapor to yield accurate temperatures.

• Automatically compensates for changes in target emissivity or varying distance from the
target to detector.
• The target does not need to fill the detector’s field of view to accurately measure the
target temperature, allowing flexibility of pyrometer location and target position
variability. An accurate measurement may be made with as little as 10% of the
pyrometer field of view used.
In one-color pyrometer, a single reading is taken and the temperature is derived from the
radiation energy. This works under the following conditions:
• If the emissivity is known and constant
• The object fills the entire field of view
• There is no interference from smoke or dust.
Two color systems measure the ratio of two readings and calculate the temperature from the
ratio rather than the absolute value of readings. This minimizes the effects of emissivity,
optical interference and partial views of the target.
Notes:
• The energy from spectral radiation
increases with higher temperature.
• These curves do not intersect. The
spectral radiation has higher energy
at all wavelengths.
• Each curve has one peak, and these
peaks move towards shorter
wavelengths as the temperature
increases. (Color shift)
• In blackbody radiation, the emitted
energy is only dependent on
absolute temperature.

If the object remains at a stable temperature, the ratio of the radiation energy remains constant.
When the target temperature varies, the two wavelength ratio will remain the same. However,
the slope of the ratio change differs when measuring different objects (like metal and
non-metal), so a two-color slope coefficient is needed for correction.

3. Location
3.1 Sensor Location
The Logika PMP-716 Pyrometer should not be used above a heat source for extended periods of
time. Avoid direct exposure to water vapor or excessive dust or smoke
The Logika PMP-716 should be used close enough to the target to allow enough infrared energy
to reach the detector in order to provide a strong signal, but far enough from the target to
minimize the amount of heat that reaches the enclosure’s electronics.
Use Figure 3.1 to determine the PMP-716 Pyrometer’s field of view based on its distance from
the target. Only the intended target should be seen inside the field of view. Other infrared
energy sources such as rolls, other wire or billets could interfere with accurate readings.
Example: The pyrometer measures the temperature of a 5 mm steel wire with adjacent wires
5 mm on each side of the target. Use Figure 3.1 to determine that the pyrometer may be
centered on the target wire and placed up to 1500 mm away from the target wire line (15 mm
total clearance from interference from other target wire lines).

Figure 3.1: Pyrometer Distance Graph
3.2 Sensor Aiming
Use the pyrometer’s visible aiming laser to properly align the PMP-716 with the target.
Typically, the pyrometer should be centered on the target. At the same time, adjust the
detection spot by aiming laser to avoid interfering sources of infrared energy, including
reflection of hot metal or sunlight.
3.3 One-Color Mode
One-Color mode can be used to measure the average temperature in an area. The focal range of
the instrument is 0.5m ~ ∞ and the distance can be infinite as long as the measured area is large
enough. When selecting one-color mode, the object should completely cover the visual field;
usually 20% larger than the visual field.
This mode can be used for objects with level surfaces (no bending), with a viewing angle within
30° to the target’s surface. This surface should be physically and chemically stable (not in the
process of oxidation, gasifying or liquefying). The view to the object must also be free of
airborne particles and obstacles. When the background temperature is higher than the
measured temperature, One-Color mode can be used as long as the target fills the entire field of
view.

3.4 Two-Color Mode
Utilized when:
• Measuring small objects
• Dust, vapor or fog in the environment
• Measuring distance changes
• Part of the object is obscured.
Two-Color temperature measuring mode measures the max temperature in an area regardless
of the size of target. Since the two sampled signals will vary at the same rate, the ratio
between the two signals will not change.
Two-Color mode permits the measurement angle to be smaller than 45°. When the background
temperature is higher than the target temperature, Two-Color mode is not recommended.

Parameter 7 - Real Time Display Interval: The internal sample time is 0.1s. The setup range
for the real time display is from 0.1 to 1.0s. If set to 1.0s, the displayed value is the average
over the last ten readings (0.1s each).
Parameter 8 - Power Off Time: Default power off time is 10 minutes.
Parameter 9 - Light On/Off: LCD Backlight ON/OFF. Setup takes effect after the power is
OFF/ON.
Parameter 10 - Upper Alarm: HAL (High Alarm Limit) will be seen on the LCD display if the
temperature reading is higher than the setup value. Default is 1600°C.
Parameter 11 - Lower Alarm: LAL (Low Alarm Limit) will be seen on the LCD display if
the temperature reading is lower than the setup value. Default is 700°C.
Parameter 12 - 2C Energy Reduction: Allowed signal reduction value in two-color mode.
Setting range is 0~95%. When value >95%, it shows “OFF”, and the function is off. Default
is=95%. See chart below.
2C Energy Reduction is a threshold for verifying the validation of the measured temperature.
After the target temperature is calculated by the pyrometer, it calculates each wavelength’s
emissivity at this temperature. For each wavelength, the 2C energy reduction (100% –
Emissivity value) should not be lower than the set value. If either one is higher than the set
value, the LEDs display the lower limit temperature of the pyrometer.
This function is only used in two-color mode. The setup range is 20%-100% and the default
setup value is 95%. If the attenuation ratio is set greater than 95%, this function will shut
down; and again, the lower limit temperature will be displayed. For example, if the pyrometer
is used to detect the temperature of tungsten filament of a light bar, usually the temperature is
higher than 1500°C (2732°F). The tungsten filament (target) diameter is very small at 2mm, so
the emissivity would be very low. According to Figure 5.6, if the temperature is greater than
900°C and target size is 2mm, the 2C energy reduction should be set to 95%. This means that
as long as the emissivity value for each wavelength signal is not less than 5%, the calculated
temperature is valid. In this case, the two-color mode, can still accurately calculate the
temperature. In single color mode, it would be very hard to get an accurate target
temperature in this situation.

Minimum (Valley) Value Temperature Measuring Method
The average time duration can be set
through the controls on the back of
the unit. The instrument will calculate
and display the average value of the
varying real-time value in a selected
time interval Δt. This first-order RC
calculation can reduce the variation of
temperature.
Application: Ideal for most field
applications or if there is scale or
oxidation present.
The sampling period of Minimum
value can be set through the buttons
on the back of the unit. This
method functions similarly to the
Maximum Method, but holds the
minimum value instead.
Application: Measuring surface
temperature of liquid metals when

6.4 Two-Color Slope Coefficient
The slope is the ratio of the radiant energy from two adjacent wavelengths. Since the radiant
energy of both wavelengths will change in unison with emissivity, the emissivity factor is
eliminated.
The following slopes are approximations and will vary with the alloy material and surface finish:
For measuring the following oxidized surface metal materials, the slope is approximately 1.0.
Cobalt Stainless steel Nickel Iron Steel
For measuring the following metal materials with smooth, clean and non-oxidized surface, the
slope is approximately 1.03.

Unknown slope: To measure the temperature of other articles or materials, the slope can be set
according to the following steps:
• Use a trusted contact pyrometer or temperature probe to measure the temperature of
the target surface.
• Use average value mode of the pyrometer to measure the temperature on several
locations of the target.
• Adjust the slope of the pyrometer until the reading value equals the temperature of the
measured object.
7. Maintenance
7.1 Regular Maintenance
Regular attention to the following will ensure steady operation of the sensor:
