The sensor converts the physical quantity to be measured into an electrical signal and processes this electrical signal so that it can be easily transmitted and processed. In addition, the sensor can detect the presence or absence of an object (binary sensor). Or the sensor outputs a measured value (analog/digital sensor).
Automation Knowledge | How the sensor works
A sensor is made up of three main components

1. The detection area contains a sensing device based on a certain technology. Depending on the technology, you can choose from a variety of different sensor types depending on your application.

2. The electronic processor converts the physical quantity to be measured into a single amount of electricity.

3. The signal output contains an electronic device that is connected to a control system.
Automation Knowledge | How the sensor works

A variety of different sensor technologies help you identify and measure targets. Depending on the technology, the sensor outputs either a switching signal or a measured value.

■An inductive sensor generates an electromagnetic field that triggers eddy currents in a metal target. The sensor recognizes this change.

■A capacitive sensor generates a capacitive measurement field. If a target enters it, this measuring field changes. Sensors respond to this change.

■A photoelectric sensor (grating) consists of a transmitter and a receiver:

– Diffuse reflex sensors are used for direct detection of targets.

– Mirror reflex sensors detect targets with a reflector.

– Thru-beam sensors have a separate transmitter and receiver.

■The ultrasonic sensor emits an acoustic pulse in the non-audible range. The echo of the target is analyzed.

■Magnetic sensor can identify external magnets. The strength of the magnetic field generated by the magnet is analyzed.

■Magnetostrictive sensors detect the position of external magnets by detecting mechanical wave time measurements.
