PTFE Liquid Solid Dust RF Admittance Level Transmitter NYSP Anti
Hanging Material
Working Principle of PTFE Liquid Solid Dust RF Admittance Level
Transmitter NYSP Anti Hanging Material
Radio frequency admittance measurement technology is a level
measurement technology with unique advantages. Although it is
similar to the concept of general capacitive measurement
technology, the RF admittance technology adds driving shield
circuit and chopper circuit to the electronic unit, so it can
realize the independent measurement of impedance and capacitive
reactance. According to the calculation of physical laws, the
impedance and capacitance reactance of any hanging material are
equal, so the influence caused by hanging material can be measured
and eliminated from the total output through the phase shift of the
oscillation circuit.
Design Features of PTFE Liquid Solid Dust RF Admittance Level Transmitter NYSP Anti
Hanging Material
◎ 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
