环境试验设备参数测量──温度传感器响应时间对测量结果的影响

The Parameters Measurement of Environmental Testing Equipments──the Effect of Response Time of Temperature Sensor on Measurement Results

通过使用不同响应时间的温度传感器,测量温度箱工作空间内几何中心位置的温度波动度,确认温度传感器的响应时间对测量结果有显著的影响。提出在制订相关的环境试验设备国家标准、校准规范时,应考虑温度传感器响应时间的影响,并给出合理的响应时间范围等建议。

By using the temperature sensors with different response time,the temperature fluctuation of the geometric center position in the working space of the high temperature box is measured,and it is confirmed that the response time of the temperature sensor has a significant impact on the measurement results.It is suggested that the influence of temperature sensor response time should be taken into account when formulating relevant national standards and calibration specifications of environmental test equipment,and reasonable response time range should be given.
