5.2 Calibration condition monitoring
Optionally, the
IPS Detect can detect changes in the vibration Third-octave spectrum by
comparing actual values with calibrated threshold values. Therefore, the sensor must be
calibrated to the pump installation. Cavitation, misalignment, imbalance together with
other wrong operation modes can subsequently be easily detected.
The sensor used thresholds (RMS vibration acceleration m/s²) from the Third-octave
reference ) refer to the calibrated values and are described as signal multiplication.
After the calibration the sensor compares the actual values with specified alarm thresholds
and informs if the values are exceeded (see topic 5.3.2).
Note:
During calibration the vibration velocity is monitored in order to check if the pump is
operating in an acceptable condition. Should the vibration velocity exceed the threshold
value, then a warning (yellow LED display see topic 5.1.1) light is displayed. This would
cause the calibration to be cancelled and the system should be checked before
continuing. Upon successful calibration, subsequent mechanical manipulation of the
sensor and/or pump is no longer possible.
