Reduce maintenance, increase productivity

Pressure transmitter gives improved performance, advanced diagnostics, user-friendly interface, Selectable HART® Revisions, and SIL2 certification

Emerson Process Management has introduced a significant number of enhancements to its Rosemount® 3051 pressure products. These will help users maximise operational control, reduce the total cost of ownership and maintenance work orders, leading to improved productivity and safety.

The first of the enhanced Rosemount 3051 capabilities is a standard reference accuracy of ±0.04% of span down to a 10:1 turndown. This improvement drives the total performance in typical operating conditions to a best-in-class ±0.12% of span. The improved performance of the Rosemount 3051 enables more accurate control, allowing the plant’s operations to run closer to set levels, and increase product quality and throughput.

The most innovative new feature, Power Advisory Diagnostics, is a predictive diagnostic tool that allows users to identify electrical loop issues at the instrument or anywhere in the loop, before they cause a loss of measurement. Examples of these issues include water or corrosion in the terminal block or junction boxes, wiring problems or even a failing power supply. With a simple three step activation and guided troubleshooting, users of all experience levels can easily implement this diagnostic to help prevent costly outages and minimise time diagnosing and resolving the root cause of a measurement issue.

As part of Emerson’s commitment to making interfaces easy, it has added a Local Operator Interface (LOI) to the Rosemount 3051, designed with straightforward menus and both internal and external configuration buttons for on the spot commissioning – even in hazardous area locations. Standardising on the 3051 with LOI for pressure, DP flow and DP level applications results in simplified, consistent configuration procedures, reducing investment in maintenance tools, training and overall costs of ownership.

The company has also enhanced the Rosemount 3051 pressure products with a Selectable HART® Revision capability (HART5 and HART7). This delivers the latest features to those that are ready to take advantage of the latest HART revision, while ensuring seamless integration with any installed host, asset management system or configuration tool.

The Rosemount 3051 now offers SIL2 certification that meets the most demanding safety application requirements. This extends the time between proof tests to five years – and allows users to avoid extra shutdowns for safety testing. Emerson also provides full documentation for efficient Safety Instrumented System (SIS) compliance. Users can add Power Advisory Diagnostics to SIL2 certified transmitters to improve safety throughout their entire electrical loop.
