Mounting a P style pressure transmitter

A mounting bracket for wall or pipe mounting (2" pipe) is also available as an accessory.
Ideally, the pressure transmitter should be mounted in a vertical position to prevent subsequent zero shifts.
The pressure transmitter can also be mounted directly on the manifold.
IMPORTANT
If the transmitter is installed inclined with respect to the vertical, the filling liquid exerts hydrostatic pressure on the measuring
diaphragm, resulting in a zero shift. In such an event, the zero point can be corrected via the zero push-button or via the "set
PV to zero" command. Please refer to the [configuration section] for further details.

Sealing and screw connections

Connecting G ½ B spigot:
For sealing, a flat gasket must be used in accordance with DIN EN 837-1.
NPT threaded connection:
Seal the threads with PTFE or another approved resistant sealant.
Process connection with flush diaphragm:
Prior to mounting the device, install a welded connection or tapped hole according to relevant soldering standards (for process
connection and welded connection dimensions, refer to data sheet).

Moisture

Use suitable cables and tighten cable glands securely. The transmitter can also be protected against the ingress of moisture by
routing the connecting cable downward before securing it. This allows rain and condensation to drip down.
This is especially important for installation in outdoor areas and rooms that are exposed to moisture (e.g., due to cleaning
processes) or on cooled or heated tanks.
