摘　　要：根据JJG351-1996工业用廉金属热电偶检定规程,利用K型热电偶温度变送器、SR23岛电调节器、PAD27功率调整器、WKJ-60热电偶检定炉构成热电偶检定点温度自动控制系统。采用调节器参数自整定的方法,去寻找检定炉温度点稳定时的最佳PID参数,保证热电偶检定由低温向高温逐点升温检定时,炉温偏离检定点温度不超过±5℃,当炉温升到检定点时,炉温变化小于0.2℃/min。According to JJG351-1996 industrial metal thermocouple verification regulations,using the K type thermocouple temperature transmitter,SR23 electric regulator,PAD27 power regulator,WKJ-60 test furnace thermocouple constitute thermocouple measuring point automatic temperature control system.Using regulator parameter auto-tuning method to find optimal PID of parameter test furnace temperature points in a stable state,ensure thermocouple calibration from the low to high temperature test point by point,the furnace temperature deviation from the test point temperature does not exceed ± 5 ℃.When the furnace temperature raised to the test point,temperature change was less than 0.2 ℃ /min.
