无引线温度测量模块设计

针对温度场测量中使用常规温度传感器引线不方便的缺点,设计了一套无引线温度测量模块。该模块具有测量精度高、无需引线、使用方便的特点。测量模块配接热电阻传感器,利用参考电阻比例测量技术,大大提高了测量稳定性。测量模块采用真空隔热蓄热技术,在-65~200℃温度范围内正常工作不少于2 h,可满足该温区真空试验罐、热压罐,或其他密闭试验装置、大空间实验装置等温度场均匀性测量的需求。

Study of Wireless Temperature Measuring Module

The usual temperature sensors are inconvenient due to leading wires in temperature field measurement. Aiming at this disadvantage,a wireless temperature measurement module was designed. It has advantages such as high precision,being wireless and easy to use. The measurement module outfits a resistance thermometer and uses referenced resistance ratio measurement technology to enhance the stability. Using vacuum thermal insulation and amassment technology,this module can work more than 2 hours in- 65 ～ 200 ℃. This module can be used for measuring uniformity of temperature field of vacuum experimental tanks,thermal pressure tanks and other airtight experimental equipment or large space experimental equipment.
