What Is a Temperature Sensor?A temperature sensor is a device, usually an RTD (resistance temperature detector) or a thermocouple, that collects the data about temperature from a particular source and converts the data into understandable form for a device or an observer. Temperature sensors are used in many applications like HVand AC system environmental controls, food processing units, medical devices, chemical handling and automotive under the hood monitoring and controlling systems, etc. The most common type of temperature sensor is a thermometer, which is used to measure temperature of solids, liquids and gases. It is also a common type of temperature sensor mostly used for non-scientific purposes because it is not so accurate.
Types of Temperature SensorsThere are different types of temperature sensors that have sensing capacity depending upon their range of application. Different types of temperature sensors are as follows:
- Resistor temperature detectors
- Infrared sensors
