NYSP-M21 RF Admittance Level Transmitter For Low dielectric
constant liquid
The working Principle of NYSP-M21 RF Admittance Level Transmitter
For Low Dielectric Constant Liquid
The RF admittance level meter is mainly composed of a detection
part and a transmission part. The detection part includes a probe,
a protective casing, etc.; , Modulation drive amplifier, filter
damping link, voltage limit and voltage-current conversion circuit,
etc. According to the bridge principle, the increased capacitance
due to the rise of the liquid level makes the bridge unbalanced. At
the same time, the output voltage of the demodulator, which is
proportional to the unbalance of the bridge, is filtered and
amplified, output damped, and converted into voltage/current.
4-20mA current signal proportional to level. Whether it is a radio
frequency capacitance level meter or a radio frequency admittance
level meter, it can accurately measure the level of the medium, but
compared with the ordinary radio frequency capacitance level meter,
the radio frequency admittance level meter is more suitable for
measuring the material level, because it can The influence of
hanging material on material level measurement is well handled.
