    6.3.4 Rear wall / plug with blow-out capability The pressure gauge has a plug capable of blowing out on the rear wall of the housing (Model T5500) or a rear wall capable of blowing out (Model T6500). These act as a safety feature pursuant to EN 837-1 and simultaneously allow for temperature compensation for the housing, via a rubber membrane.

  • Page 9: Starting Up

     When connecting the device, the pipes must be depressurized.  The pressure metering pipe must be laid inclined in such a way that, for example, for measurements of fluids no air pockets can form, and for measurements of gases no water pockets. If the necessary incline is not achieved, then at suitable points water separators or air separators must be installed.

  • Page 10: Subsequent Relocation Of The Gauge (By The Customer)

     Depressurize the pressure metering pipe.  Open the bayonet ring and remove ring and window.  Hold the pointer in place while turning the screw, until the pointer (after releasing again) has the correct position.  Close the case again and pay attention to correct fit of window, gasket and bayonet ring.

  • Page 11: Check On Function, And Recalibration

    When undertaking servicing work on the device, the pressure lines must be depressurized and the plant secured against being switched on again. 9.2 Check on function, and recalibration The check on function and recalibration is carried out at regular intervals, depending on the application. The precise testing cycles should be adjusted in line with the operating conditions and ambient conditions.
