1PC Radio frequency admittance liquid level meter level meter l2000d high temperature anti-corrosion radio frequency viscous oil level meter electrostatic capacitance switch
RF admittance switch
Not affected by material adhesion, suitable for liquid, slurry, solid, particle, interface detection

working principle
The height of the material is reflected as the change of the radio frequency current between the electrode and the container wall. When the material reaches the switch point, the electronic unit responds, drives the relay to work, and outputs the switch signal. The RF admittance is equipped with a protective electrode, which can prevent the material from hanging on the electrode and cause misoperation. When the material really reaches the set point, the switch control signal is output.
