oil contamination monitor, OCM15
- advanced online particle counter

Strong & valuable knowledge - Your oil is talking!

The CJC® Oil Contamination Monitor, OCM15 sensor module measures particles and water mounted in connection to a CJC® Offline Oil Filter, used for mineral oils and petroleum-based fluids. 
Data can be online monitored via CJC® View or SCADA System. Furthermore, we offer remote online monitoring with CJC® T2render Basic or CJC® T2render Pro (optional).   


  • Earliest possible warnings of wear generation
  • Condition based maintenance
  • Avoid breakdowns and reduce severity of failures
  • Valid and reliable online oil condition data
  • Does not count air bubbles as particles
  • Increase your ROI and protect the investment 

Monitoring the smallest micron particles using the OCM15 gives the earliest possible warning for breakdowns. Major damage can be PREDICTED and PREVENTED by stopping and repairing early in the wear process. This obviously will improve PROFIT.

The OCM15 measures according to the ISO: 4406 standard. The technology is specially designed for high viscous oils and is suited to measure in oils with large amounts of air bubbles, as they are not included in the counting. The water sensor measures relative humidity (%RH) in oil. Data storage approx. 4000 time-stamped tests in the internal OCM15 memory. Via an USBi connector, data can be transferred to a PC and explored in the CJC® View Program. The OCM15 monitors upstream the filter i.e. on the dirty side.

The OCM15 is mounted on the CJC® HDU 27/- filter base. Due to this, the flow will be stable over a large viscosity range, enabling the sensor to yield accurate readings, regardless of the oil conditions. Available for retrofit.

Data & Communication
The CJC® OCM15 data is available via the integrated RS 485 Modbus RTU interface. Modbus RTU is a widely used protocol, which makes connection easy to any SCADA system.

Recalibration & Maintenance
The OCM15 should be serviced and recalibrated at least every second year by returning the OCM15 to C.C.JENSEN A/S.
