SELF-CALIBRATING INFRARED METER AND AUTOCALIBRATION PROCEDURE OF SAID METER
ES2539408
Self-calibrating infrared meter and autocalibration procedure of said meter. The IR meter can be calibrated without being transported to a calibration facility. It incorporates a heater (7) to heat the IR meter and at least one contact temperature sensor (8) to measure the temperature in the IR meter. The method comprises: performing at least one first measurement, using the IR meter, in a first temperature field; heat the IR meter using the heater (7) until obtaining a second temperature range; perform at least one second measurement, using the IR meter, in the second temperature field; calculate a degradation coefficient (beta) from the first measurements and the second measurements, using predetermined calibration equations.
- Built-in self-diagnosis and calibration system. Without the need of external intervention and avoiding any downtime. - Eliminates external maintenance and calibration costs. - Low cost technology that is easy to incorporate into current IR detectors.
