Discontinued Rosemount 1151 Transmitter
Like many great things, the lifespan of the Rosemount 1151 transmitter reached its end. In an article, Emerson’s John Berra Says Farewell, he noted:
When I first began, a transmitter was an all-analog device with all-analog circuitry, and it did one thing: It made a measurement and it pumped that measurement out as an analog value… Today, the list of things that one of these instruments can do—just the horsepower that is in there—to do not only the measurement but the diagnostics, offers tremendous benefits. But the digitization of the control room side has changed the way we operate plants.
Rosemount 3051 Pressure Transmitter
If you’re one that has had years or even decades of service for your 1151 transmitters, there are many good reasons to upgrade them to 3051 technology. Measurement accuracy improves to 0.04% of span, stability of 0.125% of URL for 5 years, rangedown of 150:1, and installed total performance of 0.14% of span. A local operator interface in the 3051 makes commissioning and maintenance right at the device without a handheld or other device possible. The device is also rated safety instrumented system applications for safety instrumented functions up to SIL 2.
Replacements of Rosemount 1151 with Rosemount 3051 transmitters are available in differential, gage, and absolute varieties with numerous process connection-types to retrofit existing or support new installations. More on the design, functions, and capabilities are on the 3051 and 3051S demo tour site or by contacting Emerson’s Rosemount product specialists.
