Principle of magnetostrictive linear displacement sensor The magnetostrictive linear displacement (liquid level) transmitter is mainly composed of a measuring rod, an electronic silo and a non-contact magnetic ring (floating ball) on the measuring rod. The measuring rod is equipped with magnetostriction wire (waveguide wire).

Pressure of hydraulic oil Monitoring Pressure transmitters, acquire pressure value of the hydraulic oil circuit system of mobile hydraulic machinery in real time, in order to generate specified hydraulic oil from pump, pressure transmitters provide pressure value of hydraulic oil to controllers, to adjust output power of hydraulic pump and motor. Inside cylinder stoke length monitoring Magnetostrictive Position Sensor, installed inside the cylinder, permanent magnet ring fixed on the piston, feedback each stoke length of cylinder from moving parts, so that the operators can know the equipment movement in real time. Temperature of hydraulic oil Monitoring In order to make sure hydraulic oil circuit system work properly in specified temperature ranges, temperature transmitters provide temperature value of hydraulic oil to controllers, to adjust output power of hydraulic pump.

Grinding The X-Y-Z profile of the grinding process needs an accurate position description on each moving axis. Profile style magnetostrictive linear position sensor is used for precise measurement with insensitivity to thermal expansion and requires no maintenance and calibration. Plasma Cutting Positioning of the plasma torch on the X-Y cutting table requires feedback devices that are less sensitive to electrical noise. Magnetostrictive Linear Position Sensor uses a non-contact permanent magnet for position reading and requires no maintenance and calibration. Removing electrical wires from proximity with the plasma torch, combined with a signal-to-noise ratio greater than 25:1 makes the ORR sensor a good fit for this difficult application. Standard industry bus communication protocols allow for easy integration in advanced CNC motion controls.

A position sensor is any device used for measuring the distance traveled by a body starting from its reference position. It measures linear or angular position in reference to a fixed point or arbitrary reference.
