The capacitive sensor is a element which converts the variation of the measured non-electricity signal value (pressure, displacement, acceleration, thickness, vibration, liquid level, etc.) into capacitance variation for non-contact and non-defective detection of metal (conductor) and nonmetal (non-conductor). It is designed with multiple circuit protection functions, abundant of output type and output functions, and potentiometer sensitivity adjustment function. The capacitive sensor features simple design, high resolution, good dynamic response characteristics, high temperature and radiation resistance. It is applicable for automatic sensing in metallurgy, petroleum, chemical, meteorological, aerospace, and other industries.
