RF admittance level switch alksp

وصف

Radio frequency admittance level switch alksp is suitable for measuring the position and height of liquid and solid, with strong versatility: it is widely used in various occasions, such as fly ash, particle, powder, liquid, viscous, conductive and non-conductive materials

The principle of
Radio frequency admittance level switch is based on radio frequency capacitance technology that would impose on the probe, radio frequency for continuous analysis of the surrounding environment, since the dielectric constant and conductivity of all media is different from the air, when the probe in contact with the medium small capacitance change is caused by circuit testing translates into switch signal output.The anti-adhesion circuit only responds to the change of capacitance caused by the change of material
level, thus eliminating the false signal caused by the accumulation of materials.
