The description of the precision temperature measurement unit for measuring temperature of the investigated samples in the low-temperature dielectrometer in the range of 0.3 − 300 K with an accuracy of 0.05 K is given. Four-wire measurement circuit on an alternating current with use of the semiconductor temperature sensor (semiconductor film resistance thermometer) in the whole temperature range is...
To meet requirements, which arise while design of equipment for research the dielectric parameters of low-loss materials in the millimeter waveband, the necessity of high-precision temperature stabilization and measurement appear. Despite the fact that a lot of attention [1,2] is devoted to this task already, it reminds still actual, due to a plenty of specific features, which each given measuring...
