A Calibration Resource for non-contact Dynamic Temperature Measurement

The national laboratory for temperature sees an increasing demand to be able to calibrate and verify different types of non-contact temperature measurement systems. In addition to the traditional objective to measure a correct static temperature, there is also a growing interest in being able to verify that the rapid temperature changes that the current measurement system can record also corresponds to the actual temperature change. The national laboratory has a number of different reference black bodies that can generate stable temperatures within a wide range. By controlling the exposure of a non-contact thermometer for a certain temperature, its dynamic properties can be determined. This exposure will be done by placing a device between the black body and the measuring instrument that can provide an opening to the black body for a defined time. The objective of the project is to develop a calibration resource in the range of -30 to 2300 ° C, which enables calibration of non-contact temperature-sensitive instruments equivalent to at least 1000 measurements / second, which means measuring times less than 1 ms.
