　　I. Working Principles

　　

　　Inductive sensors operate based on the principle of electromagnetic induction. They utilize changes in the self-inductance or mutual inductance coefficients of coils caused by measured physical quantities (such as displacement, pressure, flow rate, and vibration) to convert these non-electrical quantities into changes in voltage or current for output. When the current in the coil changes, it generates a changing magnetic field around it, and this changing magnetic field produces an induced electromotive force in nearby conductors. Inductive sensors leverage this mechanism to convert the measured non-electrical quantities into changes in inductance, which are then converted into electrical signals by a measurement circuit for output.

　　

　　Capacitive sensors use capacitors as sensing elements to detect changes in measured physical or mechanical quantities by measuring changes in the capacitance value of the capacitor. When the distance between two conductors or the medium changes, the capacitance of the capacitor changes accordingly. Capacitive sensors monitor this change in capacitance to detect parameters such as object position, displacement, and pressure.
