A thermal sensor is a technical measuring device for detecting temperatures. There are non-contact temperature sensors and temperature sensors that touch the object to be measured. Contacting sensors include thermocouples and thermistors. Non-contact thermal sensors measure thermal radiation from a heat source. Temperature sensors are used on a large scale today and are basic components of many industrial and technical processes — in plastics technology, food technology, medical technology, chemical technology and many other areas. Temperature sensors ensure that processes run and run safely in defined temperature ranges and that specified thermal requirements are met when handling high temperatures.
