Aiming at the existing problems in the dynamic calibration method of temperature sensor, Quasi‐δ pulse temperature dynamic calibration method is proposed. The Quasi‐δ pulse dynamic calibration principle was described, the characteristics of Quasi‐δ pulse function were analyzed, and the relationship among pulse width of Quasi‐δ signal, frequency range that can be calibrated, and calibration precision...
A new dynamic calibration system composed of semiconductor laser, infrared detector and calibrated thermocouple is established to conduct dynamic calibration of K-type thermocouple. The advantage of the system is the application of a laser whose rise time is nanosecond-level. With it, the dynamic calibration of thermocouple can achieve millisecond-level time constant. In the dynamic calibration process,...
