Cernox® Sensors

Cernox® features

• Temperature range of 100 mK to 420 K (model dependent)
• High sensitivity at low temperatures and good sensitivity over a broad range
• Excellent resistance to ionizing radiation
• Bare die cryogenic temperature sensor with fast characteristic thermal response times: 1.5 ms at 4.2 K, 50 ms at 77 K
• Broad selection of models to meet your thermometry needs
• Excellent stability
• Variety of packaging options, including SD package – the most rugged, versatile package in the industry
• Non-magnetic package options available (AA, BC, BG, BR)

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 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, Cernox sensors have been proven very stable over repeated thermal cycling and under extended exposure to ionizing radiation.

The SD package, with direct sensor-to-sapphire base mounting, hermetic seal, and soldered copper leads, provides the industry’s most rugged, versatile cryogenic temperature sensors with the best sample-to-chip connection. Designed so heat coming down the leads bypasses the chip, it can survive several thousand hours at 420 K (depending on model) and is compatible with most ultra-high vacuum applications. It can be indium soldered to samples without sensor calibration shift.
