What is a temperature sensor? A temperature sensor is a device utilized to calculate temperature. This can be air temperature, liquid temperature, or the temperature of solid matter.

There are different types of temperature sensors available and they each use different technologies and principles to take the temperature measurement.

The temperature sensor market is experiencing growth and is projected to reach USD 11.1 billion by 2030. 

What Are the Different Types of Temperature Sensors?

There is a countless temperature sensors, every sensor fulfilling precise requirements. Some popular kinds are included:

Thermocouples: designed of 2 unlike metals linked at one end, thermocouples generate a voltage relative to the temperature difference between the junction and the other end. Extensively utilized in manufacturing applications because of their roughness and extensive temperature range.

RTDs or Resistance Temperature Sensors function in an alike way to thermistors and calculate ohmic resistance to calculate the temperature. They are connected to a circuit in an alike way to a thermistor but they have a much wider temperature range and can measure extreme temperatures.

Thermocouples use two conductors, made up of different metals that are joined at the end to form a junction. When this junction is subjected to heat, a voltage is produced that is directly proportional to the temperature input. They are highly versatile as different metal combinations allow for different measurement ranges; however, they lack the fine accuracy of NTCs and RTD’s making them the least precise out of the three types.
Motorsport: Exhaust gas, inlet air temperature, oil temperature, and engine temperature measurements.

Domestic appliances: Kitchen appliances (ovens, kettles, etc) as well as white goods.

HVAC applications: Heating ventilation and air conditioning devices either commercial or domesticated.

The Future Outlook of Temperature Sensors

As technology improves, temperature detectors will certainly become more effective, compact, and lucrative. Addition with AI and the Internet of Things (IoT) will transform temperature screening, permitting real-time information analysis and active interventions.
