Huite RF admittance level meter

1、 Principle

The working principle of RF admittance level switch is based on the admittance characteristics of RF circuits. When the material approaches the induction coil, its presence will cause a significant change in the admittance value of the RF circuit. By detecting changes in admittance values, the radio frequency admittance level switch can determine the presence or absence of materials and control the relevant process based on the level height.

RF admittance level switch is usually composed of RF oscillator, induction coil, signal processing unit, and control unit. The RF oscillator generates stable RF signals, and the induction coil is used to sense the presence of materials and detect admittance changes through changes in the inductance of the induction coil. The signal processing unit receives and processes the RF signal transmitted by the induction coil, determines the height of the object based on the change in admittance value, and transmits the result to the control unit to control the relevant process.

II. Structure

The structure of RF admittance level switch usually includes the following components:

1. RF oscillator: As the source of RF signals, it generates stable RF signals.

2. Induction coil: Used to sense the presence of materials, usually a coil or antenna.

3. Signal processing unit: receives the RF signal transmitted by the induction coil and determines the height of the object based on the change in admittance value.

4. Control unit: Based on the height of the object, control the corresponding process, such as conveyors, valves, or pumps.
