13~35VDC High Stability RF Admittance Level Transmitter Suitable For Strong Stirring Conditions
Working Principle of 13~35VDC High Stability RF Admittance Level Transmitter Suitable For Strong Stirring Conditions
Radio frequency admittance is a new type of level control technology developed from capacitive, anti-hanging, more reliable, more accurate and more applicable, and is an upgrade of capacitive level technology. The so-called radio frequency admittance means the inverse of the impedance in electricity. It is composed of resistive components, capacitive components, and inductive components, and radio frequency is the high-frequency radio spectrum. Therefore, radio frequency admittance can be understood as the use of high frequency. Radio waves measure admittance. When the meter is working, the sensor of the meter forms an admittance value with the filling wall and the measured medium. When the material level changes, the admittance value changes accordingly, and the circuit unit converts the measured admittance value into a level signal output to realize the level measurement.
