As outlined in ResearchGate’s article, “Types of Temperature Sensors,” temperature sensors play a critical role in various industries by measuring temperature changes through physical properties. These sensors fall into two primary categories: contact and non-contact sensors, each suited to specific applications.
1. Contact Temperature Sensors:
These sensors require direct contact with the object to measure its temperature. They can be used with liquids, solids, or gases across a wide temperature range. Examples include:
- Thermometers: Used for applications like monitoring human body temperature.
- Thermocouples: Cost-effective sensors that operate on the Seebeck effect, where voltage is generated due to temperature differences in two metals.
- Thermistors: Detect temperature changes through resistance variations and are ideal for precise measurements.
2. Non-Contact Temperature Sensors:
These sensors measure temperature without physical contact, relying instead on radiation from the heat source.
- Infrared (IR) Sensors: Detect energy emitted from an object and convert it into a temperature reading via electronic circuits and calibration.
Other Specialized Sensors:
Temperature sensors are available in various designs based on their working principle, size, and temperature range, making them adaptable to diverse applications, from industrial processes to consumer electronics.
