Replacement Meterbody and Heads
T
he ST 3000 Pressure Transmitter, Models:
·
STD110, STD120, STD130, STD170
, and

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.
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.
