RF Capacitiance level switches-HC

Radio-frequency Capacitiance Type is a kind of universal material level swtich,when the sensor is installed on the tank,the electrode and wall of tank are separately equal to the two polar plates of capacitor,due to the difference between dielectric constant of testing material and air,once there are changes of material level in the tank,there will form changes of capacitance that caused by electrode and wall of tank,when the capacitance is more than the value that set by users,the relay in limit level switch will work,and then output a switching value,in this way,to alarm and control the material level.
