Emerson for Rosemount 3051 03031 LCD Display New Pressure Transmitters Low Price Terminal Supply

What is the Rosemount 03031 LCD Display (LCD Meter)?

• The 03031 “LCD meter” is a local display module designed for Rosemount transmitters (such as the Model 3051) to show process readings and diagnostic messages locally.
• It is not a standalone transmitter; rather, it is installed on or integrated into the transmitter electronics housing as a visual readout.
• The display module is often offered in “meter kit” form (which includes the display plus mounting and interface parts) or “meter only” form, depending on how the transmitter housing is configured. For example, part number 03031-0193-0103 is a “meter only” version for an improved-style housing.

Key Features & Capabilities

From Rosemount’s documentation:

Common Part Numbers / Variants

Some variants / kits you may come across include:

• 03031-0199-0001 — low power LCD display assembly (4–20 mA HART / 1–5 Vdc)
• 03031-0199-0021 — LCD display with stainless steel cover version
• 03031-0193-0103 — meter only (no housing cover) version for an improved style housing
• Other meter kit variants: 03031-0193-0101, 03031-0193-0111, 03031-0193-1101, 03031-0193-1111 etc., matched to different transmitter housing styles

How It’s Installed & Used

• The LCD meter is mounted on the electronics board side of the transmitter housing. It connects via a 10-pin interconnection header.
• To install, one must remove transmitter covers, install jumpers (alarm, security), insert the new meter into the header, secure it with screws, and attach an extended cover.
• After installation, the meter must be configured (scale, units, decimal point, etc.) using a HART communicator (e.g. Model 275) or AMS software.
• Because the meter is ESD sensitive, special handling precautions must be observed when installing or servicing it.

Use Cases & Benefits

• It gives local, real-time display of process variable (pressure, level, flow) without needing to connect to a control room or external display system.
• It supports on-site diagnostics, letting users see alarm or error codes immediately.
• The user-configurable scaling feature allows you to present the reading in meaningful engineering units or custom scales (e.g. flow) even if the transmitter’s analog output remains linear.
• Because it is designed by Rosemount for their transmitters, it integrates cleanly and reliably with their devices.
