80mm Magnetostrictive Displacement Sensor for servo cylinder

Magnetostrictive linear displacement sensor with measuring range 80mm is used for the piston position preset and feedback, such as the piston position of servo cylinder. Magnetostrictive sensors also can be used in most industrial automation systems.

Tips: Working principle of magnetostrictive sensor
Magnetostrictive displacement (liquid level) sensor is mainly comprised of measuring rod, electronic bin, non-contact magnet ring or floating ball skewered on the measuring rod. Magnetostrictive line (waveguide) is installed in the measuring rod. The measuring rod is made of non-conductive magnetic stainless steel, and protects the waveguide reliably. When it works, the electronic circuits in electronic bin generate one start pulse, which also generates one rotational magnetic field advancing along the waveguide while transmitted in waveguide. When this magnetic field encounters into the permanent magnetic field in magnet ring or floating ball, magnetostrictive effect will be generated. Thus, the waveguide becomes twisted promptly. The twisting is sensed by the enabling mechanism installed in the electronic bin and also changed to the corresponding current pulse. Through the time difference between the two pulses calculated from the electronic circuit, the detected displacement and liquid level can be measured precisely.
