What are the principles and applications of temperature sensor

A temperature sensor is a device that can sense temperature changes and convert them into measurable signals. Its working principle is based on various physical effects, such as the thermoresistance effect, thermocouple effect, and thermistor effect, etc.

Thermoresistance Temperature Sensor

Thermoresistance temperature sensor utilize the property that the resistance value of metals or semiconductors changes with temperature.

When the temperature rises, the resistance value of metallic thermoresistors increases linearly, while the resistance value of semiconductor thermoresistors changes more significantly and usually shows a nonlinear relationship. By measuring the change in resistance value, the temperature change can be indirectly known.

Thermocouple Temperature Sensor

Thermocouple temperature sensors are based on the Seebeck effect, which states that when two different materials form a closed circuit, an electromotive force will be generated if the temperatures at the two junctions are different.

The magnitude of this electromotive force has a specific functional relationship with the temperature difference, allowing the temperature to be determined based on the measured electromotive force.

Thermistor

The thermoresistance effect is a property widely possessed by materials, while thermistors are based on special thermosensitive materials.

Thermistors are highly sensitive resistive devices whose resistance values change significantly with temperature and usually show a nonlinear relationship.

Thermistors are divided into positive temperature coefficient (PTC) and negative temperature coefficient (NTC) types. Among them, the resistance value of NTC thermistors decreases as the temperature rises, and they have the characteristics of high sensitivity and fast response speed.
