Sensors in Industrial Automation


Thermocouples are a widely used type of temperature sensors. It gives a mV output which is proportional to the temperature of the junction. They are cheap and interchangeable, have standard connectors, and can measure a wide range of temperatures.

Linear Transducer

Measures linear distance uses potential division as measuring principle an encoder is used for the angular motion.

Load cell

Force transducers are used in all industrial weighing applications.

Humidity sensor

Humidity sensors are used in all climate control processes.

Pressure sensors

Uses the strain gauge principle to measure pressure.

Level sensors

Measures the level of a liquid/solid in container.

Proximity Switches

Usually used to detect material in a conveyor. Gives a digital output according to the sensing of material. There are 4 types, Capacitive, Inductive, Magnetic and photoelectric.
