This sensor uses a magnetostrictive wave guide and a position magnet that is installed top of the piston in the hydraulic cylinder. To withstand the harsh underwater conditions, the sensor’s housing is completely sealed and tested to exceed IP68 and IP69K rating. The sensor has also been tested to be shock and vibration resistant.
The PCST27 has an operating pressure rating up to 5800 psi and a measurement range up to 19 ft, and it can be fitted to the majority of hydraulic cylinders. The sensor is available with analog output of 0-10 V, 4-20 mA or alternatively with a digital pulse output Start-Stop or Synchronous Serial Interface (SSI).
In addition to the compact design, this sensor is available with either 34-in. 16 thread or M18x1.5 thread for easy installation. The PCST27 is rated to tolerate 100, 50-G 11-msec shocks according to EN60068-2-27:1993. In case of malfunction, the electronic circuit and wave guide can easily be done without bleeding the hydraulic fluid. This precise position sensor also has a full scale linearity rating of ± 0.02%.
