摘要:

介绍一种能对热电偶进行动态校验并能测量动态温度的基于微机数据采集的一体化系统。该系统利用电加热法对热电偶的时间常数进行在线校验,同时还可进行温度测量。

关键词: 热电偶, 动态温度, 测量, 在线校验, 时间常数, 动态补偿

Abstract:

An integral system is presented based on a microcomputer data acquisition, which can be used in on line checking of the time constant of thermocouples and measuring of dynamic temperature.Time constant of thermocouple is checked on line with an electric heating method, and with the same thermocouple temperature is measured.

Key words: thermocouple, dynamic temperature, measurement, on-line checking, timeconst ant, dynamic compensation
