Purpose
This product is a differential inductive linear displacement sensor with a unique coil structure design, enabling a larger detection range in a smaller size space. 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 component into a voltage signal that the control system can recognize changes in. It is mainly used for detecting the position of the moving iron of the electromagnet or the main valve core.
