Purpose
This product is a differential inductance induction linear displacement sensor, produced with the technology of BSO from Germany. It is used in conjunction with a measurement demodulator in a DC 24V control circuit. The sensor feeds back the inductance change caused by the position change of the movable iron core to the demodulator, which then converts the inductance change into a voltage signal and outputs it. Mainly used in hydraulic closed-loop control systems, its working principle is to convert the displacement of the sensing core contacted or connected by the detected components into a voltage signal that the control system can recognize changes in. It is mainly used for detecting the position of the main valve core and the inclination angle of the plunger pump port plate.
