The product introduction
RF admittance level controller is base on the RF capacitive technology. Putting a wireless electric frequency to the detector, and through continuous analysis, the affect of surrounding inviroment is fixed. The energized detector and container skin consist of f two polar plate of the capacitor. The detector insulator and surrounding atmosphere turn into the medium materials, all materials have specific inductive capacity. The specific inductive capacity is above the atmosphere. When the atmosphere is replaced by other material, the capacity effect should be reinforced,resulting of changing the impedance of application situation, so the change of capacity value produces the change of impedance. The affect is measured by the circuit,which is compared with the reference datum which built by sensitivity setting(circuit).
The correct setting of sensitivity will affect the correct change of sensor output. The anti-adhesion circuit of the detector could make the hanging material of the detector to be ignored, or it could affect the sensitivity breakdown. Anti-inhesion circuit is used to the electric potential with the same wireless electric frequency which is added to the transduce detector. Because the circuit could not flow under the same electric potential, the anti-adhesion circuit usually flow through the circuit of the energized detector flowing from the cumulate material to the container skin. For this, the material measured is energized material and not the cumulate material.
LC2000 level controller is developed by us who absorb American and Germany RF admittance technology.
The electric circuit of LC2000 applies to the anti-adhesion circuit which could detect the real level at the same time, also could clean the signal affect of the adhesion and hanging frauds surrounding the detector.
LC2000series could detect the container contain the material(high level) or no contain the material(low level) based on the RF admittance transduce working principle. It oucld set the breakdown alarm of the high or low level module.
