Calibration of infrared temperature sensor
Infrared temperature sensors are widely used in various non-contact temperature measurements such as infrared thermometers. This type of temperature measurement product needs to be calibrated using a blackbody or surface source during the production and calibration process.
At the same time, infrared temperature sensors often cover a very wide temperature range. When performing multi-point calibration, different temperature points need to be set according to the range. Even for some portable surface source products, it takes at least 10 to 20 minutes to set the temperature and reach stability. Completing the calibration of a temperature sensor may take half a day. For some infrared temperature sensor manufacturers, more efficient temperature calibration has become an important factor in improving product competitiveness.
For batch calibration work, multiple blackbodies or surface sources can be used to form a production line, and different numbers of standards can be selected according to different temperature gradient requirements. The temperature sensor to be calibrated can be quickly moved by a slide rail and calibrated from low temperature to high temperature within a few minutes. Combined with automated calibration software and actuators, fast and fully automated calibration of infrared temperature sensors can be achieved.

It can cover a range from -15 ° C to 500 ° C, and with the 9133 low-temperature surface source, it can achieve temperatures as low as -30 ° C. If combined with high-temperature blackbody products, the high-temperature range can be extended to 1200 ° C. The following diagram illustrates a 418X large-area surface source, using 11 tabletop sources that can form 10 temperature gradients, achieving temperature calibration from -15 ° C to 500 ° C.
