NYSP-M17 High Sensitivity RF Admittance Level Transmitter With Unique Driving Shield Circuit Design
The working Principle of NYSP-M17 High Sensitivity RF Admittance Level Transmitter With Unique Driving Shield Circuit Design
Radiofrequency admittance measurement technology is a level measurement technology with unique advantages. Although similar in concept to general capacitive measurement technology, RF admittance technology incorporates Driving-shield circuits and chopper circuits into the electronic unit, thus enabling separate measurements of impedance and capacitance. It can be calculated by the laws of physics that the impedance and the capacitance of any hanging material are the same, so the effect of the hanging material can be measured and eliminated from the total output by the phase shift of the oscillation circuit.
Design features of NYSP-M17 High Sensitivity RF Admittance Level Transmitter With Unique Driving Shield Circuit Design
