Overview of inductive sensors
Function, construction and technologies of sensors
A sensor consists of three main components:
(1) The sensing section contains the sensor itself which is based on a particular technology. The variety of technologies means you can select a sensor technology which fits your application.
(2) The processing circuitry converts the physical variable into an electrical variable.
(3) The signal output contains the electronics connected to a control system.
The various sensor technologies help you in detecting or measuring objects. Depending on the technology the sensors output a switching signal or a measurement value:
