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
◎ anti hanging: the unique driving shield circuit design improves
the anti hanging ability
◎ power supply range: power supply working range: 13 ~ 35vdc
◎ probe process temperature: - 100 ℃ ~ 800 ℃
◎No dead zone measurement, can be applied to a large range of
material level measurement occasions of more than ten centimeters
or even several centimeters
◎The maximum measuring range can reach hundred meters, even
hundreds of meters
◎Viscous material interface measurement is a great advantage of
this instrument
◎stable and reliable output, resistant to fly ash, falling
material, water vapor, crystallization and wax
◎no movement, no parts easy to wear, no regular cleaning,
maintenance and debugging
