Fluid Property Sensor

Level of dissolved water in oil is a critical data for oil system management as water consumes oil additives that can result in severe mechanical damages due to degradation of lubricant properties. Just released by Measurement Specialities, the HTM2500B3C4OIL provides a voltage output with the maximum water content sensed being the saturation level of the liquid. Typical saturation levels of lubricants and oils are between 500 and 1000ppm. For ease of interpretation look-up tables are provided via datasheet documentation that converts voltage output to water in oil content. A temperature sensor is embedded in each unit that features an accuracy of ±1°C. The device features a 30 mm diameter aluminum alloy port with O-ring seal and a 4-pin integral connector for easy installation. Direct interface with microcontrollers is an optional feature. Customized versions such as specific calibrations are available upon request. The sensor’s fast response combined with reliable operation in fluids under pressure make it suitable for a wide variety of applications in the industrial or truck and automotive markets.
