Rf Admittance Level Meter Operating Principle
Traditional capacitive material level meter, with the level rising,
material covered probes, value of capacitance circuit between the
probe and the medium (conductive material) or between the probe and
the tube wall capacitance (insulation material) increases.Due to
the change of level imbalance led to a capacitance bridge, so the
change of capacitance value depends on the dielectric constant of
the material being tested.Then through to the signal detection,
amplification, and finally the corresponding signal
output.Capacitive material level meter, however, there are some
disadvantages, especially when the probe is hanging will seriously
affect the measurement result.
Radio frequency admittance measurement technology is level
measurement technology has unique advantages.Although with the
general concept of capacitance measurement technology are similar,
but the rf admittance technology in electronic unit joined the
Driving - shields and chopping circuit, thus can realize impedance
and capacitive reactance measurement alone.Through the calculation
of the laws of physics, any material is equal to the size of the
capacitive reactance of the impedance, so by the hanging can be
measured and the influence of by phase-shifting oscillation
circuit, remove from the total output.
Rf admittance level meter sensor installed in the loading of the
tank, through the probe level change caused by the change of the rf
signal.Driving - shields of probe end can prevent radiofrequency
current formed by hanging loop, ensure the accuracy of the
instrument measurement.
Rf admittance technology of high precision measurement results, and
is not affected by the probe hanging, is currently the most widely
used occasions a measurement technology.From low temperature to 100
℃ to 800 ℃ high temperature, from vacuum to 6.3 MPa pressure
situations, from ultra short range to large scale, can the normal
application, and can be applied to different types of material.
