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

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

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

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

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

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

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

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)
