Edge of Innovation: New Capabilities That Improve the Rosemount TM 3051 Pressure Transmitter User Experience.

Process automation professionals are aware of the unique history of the RosemountTM 1151 Pressure Transmitter. It appeared on lists of the top 100 American-made products twice. It changed Rosemount Engineering Co., which is now Emerson, from a supplier specializing in aerospace to an industrial automation firm. The Smithsonian Institution even has showcased the RosemountTM 1151 Pressure Transmitter.

The RosemountTM 3051 Pressure Transmitter was designed to improve the lives of process automation professionals when it first came out in 1988, and over the past 35 years, Emerson has been constantly improving the RosemountTM 3051 Pressure Transmitter to keep up with the rapid improvements in digital technology.

While the transmitter has undergone numerous upgrades over the years, Emerson recently unveiled the most significant update since its original design. With an emphasis on efficiency and safety, the latest advances mentioned in the following pages demonstrate how the updates bring the user experience into the modern day. With a dynamic graphical display, easily accessible data, Bluetooth® connectivity, a new user-friendly interface, and extensive diagnostics capabilities, the updated RosemountTM 3051 Pressure Transmitter caters to a younger generation of engineers, particularly mobile workers, while remaining familiar to existing users.

The RosemountTM 3051 Pressure Transmitter user interfaces have been redesigned to provide a simplified, task based menu structure with common navigation across different hosts and configuration tools for a faster, more intuitive user experience. The new, high contrast, graphical, and backlit display can operate in eight different languages, and utilizing visual icons relays more information with the added clarity that gives users better insight into transmitter status.

Keeping the Coplanar Process Connection

One thing that customers will find familiar with the RosemountTM 3051 is the RosemountTM CoplanarTM design of the device. Emerson pioneered the Coplanar process connection with the RosemountTM 3051, which features two process connections at the bottom of the pressure transmitter. Because it can be positioned on a single process flange, the mounting becomes lighter in weight than traditional biplanar styles which also limits flexibility. Furthermore, heat, vibration, and electrical noise, as well as other disturbances, can be isolated when using a Coplanar design.

Also, the coplanar design protects the transmitter from static pressure. But the most important element of the Coplanar connections is that the configuration makes it possible for the RosemountTM 3051 Pressure Transmitter to be a completely integrated application solution for an expanded market.

Enhanced Capabilities of the RosemountTM 3051 Pressure Transmitter

Bluetooth Connectivity: New Bluetooth technology simplifies configuration and service tasks without having to physically connect to a device, making maintenance safer by eliminating the need to climb ladders or tanks, get hot work permits, and reduce time in hazardous locations. With a few simple inputs and built-in password protection, users will have an encrypted data connection from the transmitter to their mobile device or configuration tool.

Backlit Display: The brand-new display on the transmitter boasts a backlit, high contrast, graphical screen that assures ease of use under any lighting scenario. It is equipped to convey information in eight diverse languages. Visual symbols provide a clearer comprehension of the transmitter’s status, enhancing user-friendliness.

Improved User Experience for Differential Pressure Solutions: The transmitter upgrades also include capabilities for dynamic variable configuration, allowing output of dedicated flow, level, or volume variables, something that has historically been limited to flow meters and level devices.

Now operators can easily configure the device to measure flow rate or track total flow, measure Level in any installation with simpler built-in configurator steps, and measure Volume for common tank geometries or even customized tanks that require a strapping table.

Diagnostics: The RosemountTM 3051 helps identify issues in electrical loops and impulse lines using built-in diagnostics. If not identified, these issues could result in the control system receiving incorrect measurements, potentially leading to safety and quality compromising decisions. When the transmitter identifies an issue through the diagnostic capabilities, it enunciates that back to the control system, displays it clearly on the graphical display, and adds that diagnostic event to its built-in diagnostic log which allows users to always know the device status, even when not connected to the device. These capabilities help service technicians address potential problems faster by detecting and communicating them early when they can still be corrected before they jeopardize people’s safety, operations, and the environment.

Today’s labor force expects technology to be intuitive, mobile, and responsive. With an enhanced graphical display, Bluetooth wireless technology, and better overall usability, Emerson’s RosemountTM 3051 Pressure Transmitter meets expectations to modernize operations – making it safer to interact with field equipment and more efficient to manage maintenance and service.
