What is the working principle of RF admittance?

Radio frequency admittance is a control system developed from capacitive sensors. It is a new material level control system that is anti-hanging, safer, more reliable, more accurate, and has a wider range of applications.

It is an upgrade of capacitive sensor level technology. As the so-called radio frequency admittance, the meaning of passive network is the final characteristic impedance in electricity. It is comprehensively composed of resistive components, capacitive components, and inductive components. Radio frequency is the high-frequency electromagnetic spectrum, so radio frequency admittance can understand the use of high-frequency electromagnetic waves to measure passive networks. When the instrument panel is working, the controller of the instrument panel, the irrigation wall and the measured material generate a passive network value. When the material level changes, the passive network value changes accordingly, and the power circuit unit converts the measured admittance value into a material level signal. Export to achieve level measurement.

The radio frequency admittance technology used in the radio frequency admittance level gauge overcomes the problem that the capacitive sensor level switch cannot eliminate the influence of conductive hanging materials. It has the following characteristics:

1. The radio frequency admittance level meter has strong versatility: it is suitable for various places and can detect particles, fly ash, conductive and non-conductive liquids, and viscous materials;

2. Radio frequency admittance level meter anti-adhesion power supply circuit: The unique anti-adhesion power supply design can remove the adhesion of materials and cause forged false signals;

3. Power loss safety mode: low or high fault alarm. Adjustable on the spot.

4. The level instrument panel is safe and reliable in operation, and all technical indicators have reached the international level of similar products. It is widely used for alarm and control of liquid, slurry, dust, material level and two liquid interface levels. In addition, the product adds on-site working status indication, making it a cost-effective, stable, safe and reliable level switch.
