handheld vibration meters



High performance sensor High performance sensor

Supplied with integral cable connected 780FM-2-J88C Meggitt sensor

− Sensitivity: 100 mV/g − Rugged, coiled integral cable protects against cable tear

Sensor offers long term stability through proven design and manufacturing

− Hermetic seal − Case isolated − ESD and reverse wiring protection

2 pole magnet mount



Taking a reading

Using the magnet mount, place sensor on a rigid part of the machine as close as possible to the desired measurement point

− For best results sensor should be placed gently onto measurement point by rolling the magnet onto the machine

− Avoids sudden shocks seen as large acceleration peaks by the sensor and takes some time to die away

Overall vibration numbers screen displayed − View of machine’s vibration condition

Three color coded values − ISO value − Bearing noise in BDU − Total g



Reading the display ISO values

ISO value (in mm/s or inch/s) is the RMS (average) of the vibration velocity in the frequency band as specified by ISO 10816-1 standards.

− 10 Hz – 1 kHz (600 - 60,000 RPM) − 2 Hz – 1 kHz (120 - 60,000 RPM

Correct frequency band is automatically selected based on running speed ISO value background is color coded to ISO 10816-1 vibration velocity level chart

− Indicates the condition of the machine according to the size and type of machine selected



Reading the display Bearing noise

High frequency vibration Represented in Bearing Damage Units (BDU)

− 100 BDU corresponds to 1g RMS (average) vibration measured above 1 kHz

− Shows the wear state of bearings

11



Reading the display Bearing noise

The higher the number, the more worn the bearing − 1 g of high frequency vibration (100 BDU) corresponds to a relatively high

level of bearing noise, indicative of damaged bearing Bearing noise is roughly equivalent to a percentage of bearing wear Displayed bearing noise levels

− Red: above 100 BDU − Amber: between 50 and 100 BDU − Green: below 50 BDU

Customizable BDU alarm levels

12

>100 BDU 50-100 BDU <50 BDU



Reading the display Total acceleration

RMS (average) value of the total vibration acceleration over the entire frequency range

− 2 Hz to 10 kHz Units of g

− Earth’s gravitational constant − 1 g = 9.81 m/s2

13



Reading the display Displacement

Distance a point on a machine travels from the top to bottom of a vibration cycle RMS displacement is shown in place of velcoity reading on a blue background

− mm or thou Valuable when monitoring slow speed equipment

− Fans − Blowers − Mixers − Paper rolls

14



Vibration analysis

Displays running speed of machine − Entered manually or use strobe attachment

Vibration velocity (mm/s or inch/s) or displacement (mm or thou) − Broken into three bands

Shows vibration level in frequency ranges based on multiples of machine run speed

− 1X = unbalance − 2X = misalignment − 3X = looseness

15



Vibration analysis 1X = Unbalance

Vibration in the frequency band based on the running speed is usually indicative of how well balanced the machine is High vibration at the running speed indicates machinery is out of balance Even very well balanced machines show some vibration at running speed

− Should be quite low − Less than 2.3 mm/sec or 0.09 in/sec for a medium sized machine

16



Vibration analysis 2X = Misalignment

High level of vibration in the frequency band centered at twice the running speed is a possible indication of misalignment. Shaft misalignment can result in a double peak in the waveform due to two different center of gravity (one from each shaft) Accelerometer picks up a peak as each center of gravity passes by

− Two positive and two negative peaks each revolution of the shaft − Gives rise to a vibration signal at double the running speed of the machine

17



Vibration analysis 3X = Looseness

High vibration in the frequency band centered at three times running speed indicates something may be loose

− mounting bolts − weak foundations

Not common to see third order vibration unless there is structural looseness that is being excited by the vibration of the machine

18



Vibration analysis Frequency spectrum

Range from 0 to 1 kHz Peak heights indicate the RMS vibration level at each frequency point

− mm/s or inch/s Right hand readings

− Frequency (Hz, CPM or RPM) − RMS vibration level (in mm/s or inch/s)
