Due to use of hydrogen, extremely low-temperature measurement during transport and storage is gaining an ever-greater relevance. For this application, with the CryoTemp design,WIKA provides the most suitable option for all relevant temperature measuring instruments.
In laboratory trials, resistance thermometers (Pt1000) and thermocouples (type E) were tested for their suitability in cryogenic applications. The special design of the CryoTemp features a high accuracy of +/− 3 Kelvin at minus 253°C

Special features
■ Sensor ranges from -196 ... +600 °C [-320 ... +1,112 °F]
■ For many variants of temperature transmitters including field transmitter
■ For mounting in all standard thermowell designs
■ Spring-loaded measuring insert (replaceable)
■ Explosion-protected versions (option)
