Miniature thermometers now also with CSA seal of approval for “Ex i”

Klingenberg, December 2015

New certificate for the intrinsically safe versions of the new miniature resistance thermometers from WIKA: The models TR21, TR31 (OEM) and TR34 now also have the CSA test mark for ignition protection type Ex i.

The seal of the CSA Group (Canadian Standards Association) facilitates the use of thermometers in North America. In addition, all three instrument types have ATEX and IECEx approval. The new miniature thermometers are designed for use in a multitude of industrial applications. Their design is extremely durable, and an autoclavable version is available for sanitary applications. All models are designed for a temperature range of -50 ... +250 °C.
