Brand - Capacitive Sensor - Supplier [Veckway]

Capacitive sensorIt utilizes the principle of capacitors to convert non electric quantities into changes in capacitance, thereby achieving the conversion of non electric quantities into electric quantities.Capacitive sensorNot only is it widely used for precise measurement of mechanical quantities such as displacement, vibration, angle, acceleration, but it can also be used for measurement of pressure, differential pressure, liquid surface, composition content, and other aspects.

The outstanding advantages of capacitive sensors are: simple structure, small size, high resolution, wide high-frequency response range, and the ability to be disconnected for in vivo pressure testing and touch measurement. Its main disadvantage is that the capacitance of the sensor is small, so its output impedance is high; There is parasitic capacitance, which leads tosensorUnstable characteristics; The output characteristics of variable gap capacitive sensors are nonlinear.

With respect to電容式傳感器The deep research on detection principles and structures, as well as the development of new materials, processes, and circuits, especially the development of integrated circuit technology and computer technology, have gradually overcome some of the shortcomings. The accuracy and stability of capacitive sensors are also increasing, with an accuracy of up to 0.01%.
