Mounting
case for wall mounting
{ } Items in curved brackets are optional extras for additional price.
1) The measuring ranges 0 ... 0.1 mbar; 0 ... 0.25 mbar; 0 ... 0.4 mbar are available on request.
For these measuring ranges a larger measuring cell and consequently also a case with larger dimensions is required.
2) Only with 4 ... 20 mA 2-wire, other output signals on request.
