NYSP-M20 High Reliability RF Admittance Level Transmitter With No Dead Zone Measurement
The working Principle of NYSP-M20 High Reliability RF Admittance Level Transmitter With No Dead Zone Measurement
RF conductivity measurement technique is a position measurement technique with unique advantages. Although similar to the concept of general capacitance measurement technology, the RF conduction technology adds Driving-shield circuit and chopper circuit to the electronic unit, thus enabling separate measurement of impedance and capacaciance. Calculated by the laws of physics, the impedance and toleracitivity of any pendant are equal, so the effects of the pendant can be measured and eliminated from the total output by the phase shift of the oscillating circuit.
The probe of the radio frequency admittance level meter is installed in the storage tank, and the change of the radio frequency signal caused by the change of the level is obtained through the probe. The driving shield end of the probe can prevent RF current from passing through the hanging material to form a loop, thus ensuring the accuracy of instrument measurement.
Design features of NYSP-M20 High Reliability RF Admittance Level Transmitter With No Dead Zone Measurement
