The usual temperature sensors are inconvenient due to leading wires in temperature field measurement. Aiming at this disadvan-tage, 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.
