Oil Condition Sensor

The Oil Condition Sensor has been developed to assist the plant or automotive engineer to improve the reliability of their equipment. By continuously monitoring the most common causes of gearbox and transmission failure, the sensor provides early indications of a potential problem allowing for planned investigation and remedial action to be implemented before catastrophic failure occurs.

Powerful magnets attract and retain ferrous particles in the fluid. Identification is either fine wear particles signalling fluid cleanliness or increased wear rates, or coarse failure pieces giving early indication of possible component failure.

Additionally, the sensor will provide an alarm condition of water contamination in oil, which can lead to subsequent part failure and an oil presence alarm, signalling either low oil levels or leakage.

Available with either 0-10V, 4-20mA or CAN outputs, along with a local visual alarm option, the sensors are designed to suit most data collection devices such as Dataloggers, PLC’s, ECU’s. The sensor features a simple metric thread with an O-ring seal for direct fitting into a gearbox or transmission housing.
