Magnetostrictive position sensors used in mobile hydraulics

July 2006 Sensors & Transducers

Position sensor manufacturer ASM has extended its family of magnetostrictive position sensors with the new PCST25 sensor series. This series has been designed to meet the requirements in the field of mobile hydraulics. Due to their electrical compatibility and resistance against shock and vibrations, they are best suited for applications in hostile environments, such as in the field of vehicle hydraulics. According to the manufacturer, expensive machine downtime caused by sensor failure can be minimised because these sensors are robust, reliable and ensure years of operation even in harsh operating conditions.

The compact stick design of the sensor has been developed for use in mobile hydraulics because it can be built into almost every hydraulic cylinder and the position measurement can be taken directly from within the cylinder. A selection of mounting flanges makes this sensor suitable for a wide variety of applications.

The sensor is an absolute, contact-free and wear-free position measuring system. It is equipped with analog outputs of 0 to 10 V or alternatively 4 to 20 mA to enable integration into hydraulic control systems. This new series are specified to have measurement ranges up to 5,750 mm and linearity up to 0,02%.
