Connection in Zone 1 and Zone 2

Tetraedre has developed intrinsic safety barriers that allow you to connect a TRMC to a meter, probe or sensor located in Zone 1 or Zone 2. This allows you to connect a PC or controller to a corrector or sensor. These safety barriers, called TSB-31, are certified for operation in Zone EX 1 or Zone EX 2.

Several models according to risk area

For optimal use, Tetraedre offers several models of barriers, either for Zone 1 or Zone 2. If you do not need a TRMC but need a safety barrier, you can contact us to ask for a quote.

Barrier without electricity

The TSB-31 safety barriers have a considerable advantage: they operate without electricity.
