Temperature Sensors
Introduction
Temperature sensors are used in a variety of applications such as food processing, HVAC environmental control, medical devices, chemical processing, and automotive under-hood monitoring (such as coolant, air intake, cylinder head temperature, etc.). Temperature sensors measure temperature to ensure processes are maintained within specific limits for safe application execution, or to ensure compliance with statutory regulations when dealing with extremely high temperatures, hazardous or inaccessible measurement points.
There are two main types of temperature sensors: contact and non-contact
Contact sensors include thermocouples and thermistors, which will touch the object under test during measurement; non-contact sensors will measure the temperature radiation released by the heat source to determine its temperature, non-contact sensors Sensors measure temperature from a remote location and are often used in hazardous environments.
