NYSP-Z21 Low Cost Digital RF Admittance Level Transmitter for Liquids in High Pressure Environments


NYSP-Z21 Low Cost Digital RF Admittance Level Transmitter Working Principle


RF conductivity measurement technology is a level measurement technology with unique advantages.Although the concept is similar to the general capacitance measurement technique, the RF conductivity technique incorporates a driver shield circuit and a chopper circuit in the electronic unit, so impedance and capacitance resistance can be measured separately.The impedance and reactance of any pendant are calculated by the laws of physics to be equal in magnitude, so the effect of the pendant can be measured and eliminated from the total output by phase shifting of the oscillator circuit.


The probe of the radio frequency conductivity liquid level meter is installed in the storage tank, and the radio frequency signal change caused by the liquid level change is obtained through the probe.The Driving-Shield end of the probe prevents the RF current from forming a loop through the hanging material, ensuring the accuracy of the measurement.
