Combined Oil Condition & Moisture Sensor

The CMT Combined Oil Condition and Moisture Sensor goes beyond the usual protection systems. The Combined Oil Condition and Moisture Sensor is a permanent sensor for the continuous determination of the oil condition, humidity and temperature in hydraulic and lubricating oils. It permanently monitors dissolved water, temperature and oil quality at the same time. It puts you in control of your lubricant. Prompt information is given on changes in the fluid, allowing immediate actions in deteriorating operating conditions.

The CMT Combined Oil Condition and Moisture Sensor goes beyond the usual protection systems. The Combined Oil Condition and Moisture Sensor is a permanent sensor for the continuous determination of the oil condition, humidity and temperature in hydraulic and lubricating oils. It permanently monitors dissolved water, temperature and oil quality at the same time. It puts you in control of your lubricant. Prompt information is given on changes in the fluid, allowing immediate actions in deteriorating operating conditions.

Monitoring of changes in hydraulic fluids and lubricants are essential for
condition-based maintenance. Data is continuously evaluated. In that way, deterioration and changes in the oil (e.g. water leakage, oil change, …) can be indicated.

Through this, damage can be recognized or completely avoided at an early stage. This offers the opportunity to prevent machine failures as well as to prolong maintenance and oil change intervals using appropriate measures. Furthermore, by monitoring the lubricant, correctly performed maintenance work and the use of the required lubricant quality may be documented.

Supplied with a standard ¾“ thread, it can easily be integrated into a return line or the tank. The sensor is in the position to issue sequential three analogue outputs (4…20 mA) available for dissolved water, temperature and oil quality.

The sensor records the change in temperature, relative oil humidity and
relative permittivity of the fluid. The sensor can evaluate condition
changes automatically. If needed, three alarms for moisture, permittivity, and temperature can be set and communicated via analogue output (4…20 mA).
