24VDC RF Admittance Switch Anti Adhesion

Working Principle of Length Over 2m RF Admittance Level Switch Top Mounted

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

Design feature of Length Over 2m RF Admittance Level Switch Top Mounted

◎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.
