NYSP-M19 Anti-Hanging RF Admittance Level Transmitter With Large
Measuring Range
The working Principle of NYSP-M19 Anti-hanging RF Admittance Level
Transmitter With Large Measuring Range
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 radio frequency admittance level transmitter is a continuous
level measurement product based on the principle of RF
conductivity. The product has several advantages, such as high
stability, high sensitivity and a wider measuring range. Compared
with the traditional capacitive level meter, the uniquedesign can
simply and conveniently realize the instrument setting. Once the
setting is completed, it can be used normally and maintenance-free
for life. So that users can intuitively understand the operation of
the equipment, and timely deal with the problems, in complex
industrial occasions is also as safe and reliable.
