Destination
New type temperature sensors (in comparison with the existing analogues) are advanced devices with minimised influence of self-heating and noise for temperature measurement, with enhanced sensitivity in low temperature range, accuracy and reproducibility. Sensors are recommended for high-precision temperature control and measurement.
Description
These sensors are advanced devices with high accuracy, reproducibility, radiation resistance, and easily adaptive with electronic equipment when operating with long signal lines. The developed sensors have provided most reliable and accurate temperature measurement for the objects which are operating under conditions of extreme influences.
The sensors have successfully been applied to temperature monitoring of the object “Shelter” under high irradiation background conditions, and for control at cryogenic temperature regimes during the fueling of the rocket Zenit-3SL.
