Three Fluke's 5641 and three 5610 thermistors were tested for 24 hours in Fluke's 7008 calibration bath in the first step. In the second step  the performances of these two thermistors in steady state and transient state air temperature environments were tested for 8 hours separately. The results illustrate that  two of the 5641s were airproofed in a temperature well controlled tube  when steel tube enclosed precision thermistors are used in air temperature measurement  there are unstable departures from each other with a maximum 8.8 mC in constant air medium and 27 mC in temperature changing air medium. The transient-time errors are too large to show the true amounts of temperature changes for air temperature measurement. 2011 IEEE.   Transient Performances of a Two-Pass Gas-to-Gas Crossflow Heat Exchanger 期刊论文  OAI收割 JOURNAL OF THERMAL SCIENCE, 1998, 卷号: 7, 期号: 1, 页码: 67,70 Song-Junxiao; Lin-Guiping; Yuan-Xiugan 收藏  |  浏览/下载：12/0  |  提交时间：2013/03/12 lumped parameter  transient performances  heat exchanger.
