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.
