  • To ensure the accuracy and reliability of the test results, a set of dynamic calibration device for non-combustibility test furnace of building materials was designed and developed through the study of the temperature distribution model of the test furnace. The device adopted thermocouple high-temperature detection and temperature compensation technology to realize the dynamic temperature detection of the test furnace, and the servo motor and sliding platform were designed to realize the sensor automatic positioning in the high-temperature furnace. The LabVIEW data processing technology and touch screen design were equipped to achieve calibration data processing and calibration results output. The developed calibration device was tested and its performance met the design requirements. The verification results of the calibration of each parameter of the test furnace were within the range specified by the standard, and the calibration uncertainty met the requirements for value transmission.on.
