Condition monitoring of pumps

Condition-based maintenance now becomes reality!


The SIHIdetect sensor is the ideal solution for vibration velocity measuring and for pump condition monitoring for example to detect bearing wear, unbalance, misalignment, unacceptable pipeline forces, cavitation, exceeding of max flow rate, etc.
The SIHIdetect sensor is suitable for all kinds of liquid and vacuum pumps.


- Simple to connect
- Universal use
- Visual check via LED display
- Easy Installation
- Also available as non Ex version

RMS vibration velocity
- unbalance
- misalignment
- detrimental pipe work forces
- etc.


Condition monitoring
- unacceptable operation mode for
  example cavitation, bearing wear,
  exceeding of max flow rate, etc.


SIHIvibrosoft software:
Available as an optional extra, SIHIvibrosoft software has been developed purposely for professional analysis of the data, which has been generated by the SIHIdetect sensor. Detailed evaluation of the data can subsequently be made in order to reveal very specific aspects of vibration.


Condition monitoring
- visualisation of vibration data
- frequency-specific, and/or general, threshold
  magnitudes based on calibration data
- data logging

- extracting the error memory
- sensor temperature

Data analysis
- evaluation data logging
- trend analysis for wear
- analysis of intermittent anomalies
