operational principle

In capacitive level measurement, the sensor and container form two electrodes of a capacitor. The capacitance change caused by positional changes will be transformed into a switching signal.
Using the measured object as the medium, an induction rod is used to detect the electrical capacity between the induction rod and the barrel wall (ground electrode). When the induction rod is covered by the material, the electrical capacity increases. When the capacitance matching value set by the internal circuit of the switch is reached, the circuit generates high-frequency resonance, detects the resonance signal, and converts it into switch action.

The RCS series products have undergone a brand new circuit design, upgrading analog circuits to digital intelligent circuits, greatly improving user experience International operation efficiency enhances the stability of product use, greatly improves accuracy, and easily adapts to different material characteristics.
