摘要
采用铑铁电阻温度传感器研制了一台低温温度计 ,用于对制冷机低温泵温度的测控。文中介绍了传感器的性能和仪器的设计。仪器采用了串行总线结构 ,并可以通过仪器串行通讯口更新 EEPROM中的分度表 ,因而具有较高的性价比 ,使用也相当方便。
A smart cryomatic instrument has developed to measure and control the temperature of a refrigerator cooled cryopump by means of the Rh Fe resistance sensor. The sensor performance and the instrument design are presented in this paper. Its system is provided with a serial peripheral interface and the data in EEPROM can be modified easily through RS232C after calibration,thus yielding a good ratio of performance to price and ease of use.
