Market Definition
A temperature sensor is a device that is used to measure the degree or level of heat in a substance or its surroundings. Temperature sensors can typically be classified into two types: contact and non-contact sensors.
Contact sensors: These temperature sensors need to make physical contact with the object being sensed. In contact sensors, temperature sensing occurs through conduction. Contact sensors are capable of measuring the temperature of solids, liquids, or gases over a wide range. A few examples of common contact sensors include thermocouples, temperature sensor ICs, thermistors, and RTDs. Non-contact sensors operate on the principles of convection and radiation to detect temperature changes. Non-contact sensors detect the thermal radiation that is emitted from an object and are equipped with infrared radiation sensors. The major types of non-contact sensors are optical and infrared sensors.
