Cryogenic Process Sensors

Cryogenic Systems

Cryogenic systems, such as those in superconducting magnets, quantum devices, and helium liquefaction, operate at extreme low temperatures (20K to ~77 K).

Traditional FBG optical fiber sensors are inert at these temperatures, but Proximion have developed a specialised FBG sensor which retains temperature sensitivity at cryogenic conditions.
