Displacement Sensor

Technical data: Long Stroke Sensor

The long stroke sensor is used for analogue linear measurements of industrial refrigeration compressors in connection with capacity control. The sensor is available in both a standard and an EX edition. It has a measurement travel of max. 50-2000 mm, and can be calibrated for a minimum measurement travel of 50-80mm. The sensor sends an analogue 4-20 mA signal corresponding to max. movement. The sensor is designed for harsh environments in a refrigeration system, and it can handle vibrations and high pressure up to 100 bar.

Product features

 Sturdy and reliable design with a standard 4-20 mA output signal.
 Designed for the refrigeration industry – max. pressure up to 100 bar.
 Simple calibration for the specified travel.
 Split design which makes the sensor easy to install and service. The electronic part can be easily separated from the mechanical part.
