Rosemount 3051ST In-Line Pressure Transmitter Overview
In-Line Pressure Measurement on the Scalable 3051S Platform
The Rosemount 3051ST In-Line Pressure Transmitter is the in-line, single-diaphragm member of Rosemount’s 3051S Series, a scalable platform built for gauge and absolute pressure measurement with a direct, compact process connection rather than a coplanar flange. Where the 3051T uses Rosemount’s classic transmitter electronics, the 3051ST carries the newer 3051S platform’s diagnostics and performance options through into an in-line body.
The 3051S platform is available in two accuracy classes: Classic at plus or minus 0.035 percent of span, and Ultra at plus or minus 0.025 percent of span with 15-year stability, an improvement over the classic 3051T’s 10-year stability rating. A 200:1 rangedown lets one transmitter, rated 0 to 0.3 psia up to 0 to 10,000 psia, cover a wide set of applications without reordering for a narrower span.
Both accuracy classes carry SIL 2/3 certification to IEC 61508, and support 4-20 mA HART, WirelessHART, and FOUNDATION Fieldbus output, matching the diagnostics and protocol options already available across the rest of the 3051 family.

Rosemount 3051ST Measurement Configurations
The two measurement configurations of the 3051ST In-Line Pressure Transmitter
3051S_TG
Rosemount 3051ST Gauge Pressure Transmitter
Measures pressure relative to atmosphere through a direct in-line connection, specified for line pressure and general vessel monitoring where a compact process connection is preferred over a coplanar flange.
3051S_TA
Rosemount 3051ST Absolute Pressure Transmitter
Measures pressure relative to a full vacuum, specified for vacuum and near-vacuum process conditions. Ranges from 0 to 0.3 psia up to 0 to 10,000 psia.

Applications
Rosemount 3051ST In-Line Pressure Transmitter applications
Oil, Gas & Petrochemical
Line and vessel pressure measurement in process units where Intrinsic Safety and Explosion-Proof approvals are imperative for any equipment used.
Power Generation
Boiler and steam line pressure monitoring across fossil and combined-cycle plants.
Vessel and line pressure monitoring in continuous and batch process units.
Chemical Processing
Water & Wastewater
Line pressure measurement across treatment and pumping stages.
Preventative Maintenance
A modest investment in reliable pressure measurement directly protects facility and equipment investments from unplanned breakdowns.
Explosive or Hazardous Areas
Locations where flammable gases, vapors, dust, or fibers require equipment specifically approved for hazardous-location use.
Regions We Serve
Where Instrubiz Supports the 3051ST in Canada
Alberta
Alberta’s oil sands and petrochemical facilities specify the 3051ST where a compact in-line connection is preferred over a coplanar flange. Instrubiz supplies the gauge and absolute configurations Alberta operators need for both new installations and transmitter replacements.
Ontario
Ontario’s manufacturing and process facilities use the 3051ST for line and vessel pressure monitoring across production and utility systems. Instrubiz supplies genuine 3051ST transmitters with the technical background to help confirm the right configuration.
