摘　　要：探讨并尝试了一种在现场非稳态温度场条件下对温度传感器进行有条件校准的方法。该方法将被测温度传感器与标准温度传感器置入不同变温速率的温场中,通过对采样时间的限制来消除温度传感器动态响应对校准结果的影响,通过对被测温度传感器与标准温度传感器输出数据进行采集与计算,直接获得被测温度传感器的温度偏差值。This paper studies a method for calibrating the temperature sensor under the condition of unsteady temperature field in the working condition.In this method,the tested sensor and the standard sensor are placed in a uniform rapid change temperature field with different slopes for testing.And the influence of the dynamic response of the sensor on the calibration result is eliminated by limiting the sampling time.Finally,the deviation of the tested temperature sensor is obtained by the method of mathematical calculationof the measurement results of the two sensors.
