Strong Universality RF Admittance Switch Anti Adhesion Industrial Applicatons

High And Low Temperature Resistance *6GHz RF Admittance Switch By Foam Widely Removable probe Operating Principle

RF admittance level switch is based on RF capacitor technology. Probe head receives radio frequency . By continuous analysis, confirming the impact caused by the surrounding environment. Because materials have different dielectric constants, and their conductivity is different from air. the total impedance changes as well as capacitance shift does during contact. The energized probe and the vessel wall form two electrodes of the capacitor, so the insulator of the probe head and the surrounding air become dielectric materials. When the air (with a dielectric constant of 1.0) is replaced by any other material (with a dielectric constant>1), the capacitive efficiency will be strengthened. This changes the impedance of the application. The change of capacitance value causes the change of impedance. The circuit measures the effect, and then compares with the reference data established by the sensitivity setting.

through stacked material to the vessel wall. In this case, RF admittance level switch can measure the correct level of the material.

◎ Anti adhesion: the patented anti adhesion circuit can eliminate the false signals caused by material adhesion.

◎ High and low temperature resistance; Suitable for working environment from - **4 ℃ to **0 ℃, and ceramic probe suitable for higher temperature can also be provided:

◎ Diagnosis: after power on, the instrument circuit automatically detects whether the working state is normal.
