Hengst Online Particle Monitor

The Hengst OPM II is a visual monitoring application that operates on the light-extinction principle to monitor particles online. The level of contamination and the purity trend of non-aggressive fluids can be monitored and accurately documented.

The monitor features a laser sensor and a fluid-transporting system, which operates by means of two threaded couplings.

Temperatures are measured on the electronic circuit board, alongside an operating hours counter. After the current interruption, the counter re-starts and counts the last stored time value before the interruption.

The OPM II can be integrated into external systems or operated as a stand-alone system. In some instances, data can be transferred to a PC for analysis.

Features and benefits include:


  • Cleanliness class display according to ISO 4406:99 or SAE AS4059E
  • Suitable for mineral & bio-oils; diesel fuel
  • Easily configurable from the display; has an integrated data memory
  • Nominal pressure up to 420 bar dynamic / 600 bar static
  • Nominal flow 50 to 400 ml/min
  • Operating temperature ‒20 to +80 °C
