Project Description

Capacitive Proximity Sensors

Get Best Quality Capacitive Proximity Sensors

Capacitive Proximity Sensors can be used to detect non-metal objects, such as liquids and plastics. Capacitive sensors are inspired by the electrical property of capacitance between any two conductive surfaces within reasonable proximity, and as changes in distance between the surfaces will change the capacitance value, it then reflects the change in position of a target. High-performance capacitive sensors have outputs which are very linear, stable with temperature, and able to resolve incredibly small changes in capacitance resulting in high resolution measurements of less than one nanometre. A linearization function is integrated for measurement against insulator materials. Capacitive sensors are available for a wide range of applications.
