CAP-PRS Series Capacitive Displacement Sensors CAP-PRS.200
A capacitive sensor converts changes in a measured nonelectrical quantity into changes in capacitance. It has a simple structure, small size, high resolution, an averaging effect, and high measurement accuracy. It enables noncontact measurement and can operate under harsh conditions such as high temperature, radiation, and strong vibration. It is widely used to measure pressure, differential pressure, liquid level, vibration, displacement, acceleration, component concentration, and other quantities.
