Overview Replacement Meterbody and Heads for Model STD 110
The ST 3000 Pressure Transmitter (Model STD110) is now being shipped with newly
designed meter body and process heads. If a replacement meter body is needed, it
should be ordered from the Model Number stated on the meter body nameplate. This
meter body replacement number will start with STD110S-xxx...
This new transmitter is functionally identical to previous models, with the same
specifications and intended applications (Draft Range: 10” H2O [25 mbar]).
The new version, which will continue as Model STD110, differs only in the physical
size and form of the meter body, process head, and associated components.
With exceptions noted in this addendum, information given in User’s Manual
34-ST-25-17A applies also to this newer design.
Installation, operation, maintenance, calibration, and troubleshooting tasks remain
virtually the same as for the previous version. Differences appear primarily in torque
specifications when replacing meter bodies, and in part numbering and part
recognition when replacing components or assemblies.

In Step 5, do not use the torque specification of 47.5
to 54 N∙m (35 to 40 lb-ft).
Instead, torque Flange Adapter bolts evenly to
47,5 N·m +/- 2,4 N·m (35 Lb-Ft +/- 1.8 Lb-Ft).
