Notice
- The Sensor must be fixed form-closed, to assure the correct transmission of the vibration.
- The Sensor must not be mounted on curved or coated surfaces
- The signal line should be as short as possible
- Ensure that there are no additional changeover of material besides bearing and bearing carrier
- Oscillating parts of housing are not permitted as measurement position
- Measurement should proceed in direction of load
- Mounting should be done in direction of highest velocity of vibration. As far as there are no measurement or data available mounting
o
o
should be done in 135 or 225 from A-side
- Very low diagnostic characteristic values might be caused by wrong measurement position or faulty installation of the sensor
- Measurement of RMS should not be done with sensor mounted on exposed SPM-nipple
- Changes in the setting-up area of the motor can influence the diagnostic characteristic values.
