RMF Oil Quality Sensor / Oil Quality Display


The RMF Oil Quality Sensor 2 (OQS2) puts you in control with real-time monitoring of oil degradation and water ingress. Expensive oil changes are now based on oil condition, not on historical schedule.

The sensor is a live, highly flexible and cost effective condition based monitoring solution, designed to be permanently mounted within any lubrication system on any type of machine.

Over 60 times more sensitive to oil contamination than any other dielectric constant measuring sensor, it provides real-time monitoring of water ingress and oxidation levels.

Maximise service life of oil
The requirement to implement an effective monitoring and maintenance program for lubricants in critical plant machinery has never been greater. With the escalating price of crude oil and the vast improvements that are being seen in the quality of lubricants available today, it is more important than ever for organisations to ensure that they are maximising the service life of the oil used.

Know when to change oil
Monitoring oil condition is clearly fundamental to understanding the optimal time to change. Change to early and the cost is significant, change too late and the costs can be even greater!

The RMF Oil Quality Display (OQD) is a simple but powerful device. It allows you to read the quality and temperature of the oil from a sensor without a PC.

This enables you to set up the display box on site and then be able to see the oil quality and temperature readings as required. Use an Android app to connect your Smartphone with the OQD smart via Bluetooth.

With it being IP67 rated (when connected) you do not need to worry about the need to keep it in a dry place. Also with it being made from polycarbonate it is a strong durable product which cannot be damaged easily.

The new ‘Rate of Change‘ feature allows you to easily monitor the degradation of oil over a programmable period of time.
