Temperature is measured with one or more kinds of temperature sensors. There are several available on the market today:
1. Thermocouple sensors
2. RTD sensors
3. Thermistor sensors
4. Infrared temperature sensors
A thermocouple is a sensor that is used for measuring temperature. The thermocouple is a very popular sensor to its relatively low cost, interchangeability, wide measuring range, and reliability.
Thermocouples are widely used across every industry, from factory automation and process control to automotive, aerospace, military, energy production, metals manufacturing, medical sciences, and countless more.
They have standard connector types, making them interchangeable and easy to source. On the measuring end of the sensor, they can be as simple as the two metals twisted together, or they can be enclosed within a rugged probe for use in rough industrial environments.
