The performances of two steel tube enclosed precision thermistors are tested in a well controlled air environment to determine if the thermistors have enough accuracy for 0.01C levels of air temperature gradient measurement. 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.
