Correction Method for Infrared Temperature Measurement of Petrochemical Heat Equipment Surface

Basing on the measured data of in-situ petrochemical heat equipment , a thermocouple-based tem-perature-correcting model was proposed and the relative compensation method for the interference factors was presented .Aiming at the influence from the wind speed and direction and neighboring heat equipment , the de-tailed analysis was implemented , including the establishment of correction and compensation formula .Applica-tion results show that the method proposed can effectively reduce temperature error of the infrared thermal ima -ger so that the purpose of temperature correction can be reached .
