Semiconductor transducers of temperature (thermoresistors, cryogenic sensors temperature): material - powder germanium
temperature operating range 4.2 - 300 K
sensitivity: at 300 K - 1% / K, at 77 K - 10% / K, at 4.2 K - 100-200% / K
dimensions are no more than 1х1х2 mm. They are executed on binary conductive scheme
current feeding 10 - 100 mkA
electric resistance at temperature: 300 K- 1 - 5 Ohm, 77 K-10 - 50 Ohm, 4.2 K -10 - 50 kOhm
Cryogenic temperature sensors (thermistors) can work in magnetic fields to 12 T. The admissible error in temperature measurement at the expense of magnetic resistance effect in the field 8 T does not exceed 0.02 K. At the execution in a form of quatermery conductive scheme the error is no more than 0.01 K.
