importance of thermistor mount configuration to meteorological rocket temperature measurements
A description is given of the original rocketsonde thermistor mount, consisting of a 10-mil bead suspended between two metal posts. The difficulties encountered with this mount and the subsequent development of the superior “thin-film” mount are also described. The uncertainties associated with the use of the latter mount are outlined along with their effect on data acceptance. A different approach to the original problem is described, which employs longer leads for dissipation of heat conducted to the bead. The uncertainty associated with the long lead is shown to be minimal. Preliminary results of a series of 10 rocket flights are presented. These results tend to confirm the advantages of the long lead mount.
