摘要
针对低温接收系统杜瓦设备,设计一种低温温度测量装置,从器件选型到各模块功能电路设计,都给出详细的论述。该测量装置具有软件识别分段测量功能,并且预留扩展接口,最多可同时测量8路模拟量,经过调试、校准,其已经成功应用于某高校低温接收系统杜瓦冷板温度测量,并且达到预期目的,运行可靠。
To monitor Dewar＇s temperature in low temperature receiving system,we now designed an equipment,and gave detail exposition from devices choosing to circuit designing of each functional module.This measurement equipment can sectionalization test by software distinguish.It has extend ports left and can measure eight analog quantities in the same time.After debugging and calibrating,it has succeed in applying to a low temperature receiving system for a university,and achieves its expected purpose running reliable.
