Overview Replacement Meterbody and Heads
The ST 3000 Pressure Transmitter, Models:
· STD110, STD120, STD130, STD170, and STD974
· STD924 and STD930 with Tantalum and Monel diaphragms
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 in that the working
ranges (Lower Range Limit to Upper Range Limit) and intended applications have not
changed. However, the specifications for the maximum Pressure Rating and for the
Overpressure Rating have been enhanced in all models except the draft range
transmitter. A summary of specifications is given in Table 6.
The new versions, which will continue as Models STD110, STD120, STD130,
STD170, STD924, STD930, and STD974, differ only in the physical size and form of
the meter body, process head, and associated components.
Addendum
(to User’s Manual
34-ST-25-14B)
Related
Publications
With exceptions noted in this addendum, information given in User’s Manual
34-ST-25-14B 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.
This addendum provides details for parts replacement that span a variety of
applications of the Models STD110, STD120, STD130, STD170, STD924, STD930,
and STD974.

The Maximum Working Pressure Rating and the
Overpressure Rating has been enhanced for all
models included in this addendum except for the
draft range transmitter.
For more information, refer to Table 6 in this
Addendum.
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).
In Step 8, do not use specifications for head bolt
torque given in Table 54.
Instead, torque head bolts/nuts to the specifications
given in Table 2 of this addendum.
In Step 9, the reference to Table 48 for applying
torque to head bolts/nuts should be as given in
Table 2 of this addendum.
Figure 57 illustrates the replacement parts available
for the previous design of meter body and process
heads, and Table 71 provides part numbers and
descriptions for the parts called out in Figure 57.

heads, use Figure 1 of this addendum to locate
replacement parts, and use
addendum for part numbers and descriptions.
