Due to the global use of hydrogen, extremely low-temperature measurement during transport and storage is gaining an ever-greater relevance. With the cryo design, WIKA provides a suitable option for all relevant temperature measuring instruments for this demanding application.
In laboratory trials, resistance thermometers (Pt1000) and thermocouples (type E) were tested for their suitability in cryogenic applications. The special design of the cryogenic thermometer features a high accuracy of ±3 Kelvin at -253 °C [-423 °F] as well as high reproducibility.
The test data from laboratory investigations served as the basis for calculating new polynomials for Pt1000 resistance thermometers in the range of -258 ... -200 °C [-432 ... -328 °F] which are used in the configuration of WIKA transmitters.
What is the WIKA Build ID?
The WIKA Build ID is a unique seven-digit code that temporarily saves an individual WIKA instrument configuration. The WIKA configuration can be saved, shared and used later using the Build ID.
What minimum insertion lengths are recommended, as a rough guide, for protection tubes in order to minimise the heat dissipation error?
(These standard values are only valid for static media. The gap between the protection tu ...
