Protective/separating instruments  

Functional principle
Separating instruments separate intrinsically circuits from nonintrinsically safe circuits. Differences are the kind of voltage supply as well as the size of Ex-technical characteristics values.

Applications
These instruments are used in all applications where Ex-regulations have to be met.

Functional principle
These protective instruments limit frequent failures and overvoltages in plants to uncritical values so that failures or malfunctions of the connected instruments cannot occur. The instrument selection depends on the mounting and the protecting voltage supply or the control circuit.

Applications
These instruments are used in all areas of industrial measurement technology.
