Description

Technical Field

[0001] The utility model relates to the technical field of level switches, and more specifically to a radio frequency capacitance level switch with good fixity. Background Art

[0002] RF admittance is a new level control technology developed from capacitive level control. It's anti-sticking, more reliable, more accurate, and more widely applicable. It's an upgrade to capacitive level control technology. RF admittance, the reciprocal of impedance in electrical engineering, is a combination of resistive, capacitive, and inductive components. Since radio frequency refers to the high-frequency radio spectrum, RF admittance can be understood as measuring admittance using high-frequency radio waves. When the meter is operating, the sensor, the wall, and the measured medium form an admittance value. As the material level changes, the admittance value changes accordingly. The circuit unit converts the measured admittance value into a level signal output, achieving level measurement.
