. . .4 Mounting
Mounting 266DDS pressure transmitter
The pressure transmitter can be mounted directly on the manifold. 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.
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. For transmitters without diaphragm seals, the
Vent / Drain considerations below should be taken into account.
