Understanding the Challenges of Surface Temperature Measurement Using Thermocouples

It's common to see a thermocouple taped to a surface for the purpose of temperature measurement, but you may not realize how inaccurate the results will be. This paper explains the theory behind thermocouples and illustrates some of the problems inherent to thermocouple use. In addition, the paper looks at when to use a thermocouple in combination with an infrared camera and when an infrared camera alone will give the most accurate results.

Infrared Camera Accuracy and Uncertainty in Plain Language

How accurate are thermal imaging cameras, and how are they calibrated? Understanding infrared camera accuracy and sensitivity can help clarify the value of well-calibrated thermal imaging cameras. In this paper, we use layman’s terms to explain how IR cameras are calibrated, how their accuracy is determined, and which variables can affect measurement results.

Next Generation IR Technologies Solve High Speed Automotive Testing Challenges

Product research and development on internal combustion engines, brake rotors and tires, and high speed airbags are just a few of the areas that truly benefit from high speed, high sensitivity thermal characterization testing. Unfortunately, traditional forms of contact temperature measurement such as thermocouples are not practical to mount on moving objects, and non-contact forms of temperature measurement such as spot guns – and even current infrared cameras – are simply not fast enough to stop motion on these high speed targets in order to take accurate temperature measurements.

Temperature Guns Versus Thermal Imaging Technology

Thermal imaging cameras are used for non-contact temperature measurements in companies all over the world. Another common tool for non-contact temperature measurements widely used in industrial applications is the spot pyrometer. Both spot pyrometers and thermal cameras work according to the same principle; they detect infrared radiation and translate it into a temperature reading. Thermal cameras however, have several advantages compared to spot pyrometers.

Cooled or Uncooled?
Tech Notes

Cooled or Uncooled?

Thermal imaging cameras with  a cooled detector offer some advantages over thermal imaging cameras with an  uncooled detector. However, they are  more expensive. A modern cooled thermal  imaging camera has an imaging sensor that is integrated with a cryocooler, which lowers the sensor temperature to cryogenic temperatures. This  reduction in sensor temperature is necessary to reduce thermally-induced noise  to a level below that of the signal from the scene being imaged.
