RF Capacitor Switch Measurement principle
The advanced digital intelligent compensation technology is used in the NYDR capacitive level switch to convert the liquid level change in the container to the capacitance change. There are two plates in the probe. The dielectric change changes the dielectric constant between the electrodes, and the change of the capacitance is obtained. The capacitance is converted into the pulse digital signal by the electronic plug-in. The design of alarm point and the realization of alarm action are accomplished by microprocessor.
