Cernox® thin film resistance temperature sensors are cryogenic thermometers designed for use from 100 mK to 420 K, offering high sensitivity at low temperatures and low magnetic field-induced errors. They feature fast thermal response times of 1.5 ms at 4.2 K and 50 ms at 77 K, and are stable under repeated thermal cycling and ionizing radiation exposure. Available in multiple packaging options including AA, BC, BG, BR, and SD, the SD package provides hermetic sealing, direct sensor-to-sapphire base mounting, and compatibility with ultra-high vacuum environments up to 500 K. The sensors are non-magnetic and capable of being indium soldered without calibration shift. Recommended excitation is 20 µV below 0.5 K and 10 mV or less above 1.2 K.
Cernox® thin film resistance cryogenic temperature sensors offer significant advantages over comparable bulk or thick film resistance sensors. The smaller package size of these thin film sensors makes them useful in a broader range of experimental mounting schemes, and they are also available in a chip form. They are easily mounted in packages designed for excellent heat transfer, yielding a characteristic thermal response time much faster than possible with bulk devices requiring strain-free mounting. Additionally, they have been proven very stable over repeated thermal cycling and under extended exposure to ionizing radiation.
