Rf Capacities Liquid Level Switch Working Principle

NYDR capacities liquid level switch adopts advanced digital intelligent compensation technology to convert the liquid level change in the container into the capacitance change. There are two plates in the probe, the change of the medium changes the dielectric constant between the electrodes, so as to obtain the change of the capacitance, The capacitance is converted into a pulse digital signal through the electronic plug-in, and the design of the alarm point and the realization of the alarm action are completed through the microprocessor.

Rf Capacities Liquid Level Switch Design Feature

◎The upper limit and lower limit alarm modes are flexibly set, and the user can set the normally open and normally closed contacts by themselves;

◎Both single-point and multi-point relays use high-performance imported single-pole double-throw relays. The single-point contact current capacity can reach 8A, and the multi-point type 3A. It can directly drive the alarm device within the range;

◎Adopt Teflon probe, no moving parts in the detection part, impact resistance, high temperature resistance, corrosion resistance.
