24VDC RF Admittance Switch Anti Adhesion

Working Principle of 24VDC RF Admittance Switch Anti Adhesion

The working principle of the radio frequency admittance level switch is based on radio frequency (RF) capacitive technology. A radio frequency is applied to the probe and, through continuous analysis, the effects caused by the surrounding environment are determined. Since all materials have a permittivity and their conductivity is different from that of air, the overall impedance reflected by the small capacitance shift changes when the probe is in contact with the material. Because the energized probe and the vessel wall form the two polar plates of the capacitor, the insulator of the probe and the surrounding air become the dielectric material, when the air (which has a dielectric constant of 1.0) is replaced by any other material (with a dielectric constant > 1), The capacitive effect is enhanced. Thus changing the impedance of the application. That is, the change of capacitance value causes the change of impedance. This effect is measured by the circuit and compared to a reference established by the sensitivity setting (circuit).

Design feature of 24VDC RF Admittance Switch Anti Adhesion

◎this product uses intelligent microprocessor components and difference measurement technology, which can measure water, sewage, mud and other liquids, especially can effectively and accurately measure strong corrosive media, and can dynamically compensate for environmental changes and hanging materials;

◎the operation is very simple. You only need to adjust the corresponding sensitivity knob according to the medium and use the surge delay filter;

◎ the upper and lower limit alarm modes can be flexibly set, and the user can set and select the normally open and normally closed contacts by himself;

◎High performance imported single pole double throw relays are used for single point and multi-point relays. The single point contact current capacity can reach 8A and the multi-point relay 3A. Can directly drive alarm devices within the range;

◎ PTFE probe is used. There is no movable device at the detection position. It is impact resistant, high-temperature resistant and corrosion-resistant.
