Rosemount Transmitter 3051

Main Model Families

The 3051 series is available in two primary configurations to suit different installation and application needs:

Family	Key Features	Best For	Max Pressure Range
3051 Coplanar™	Features a patented Coplanar™ flange design that integrates with manifolds, seals, and other components to form a complete pressure, level, or flow measurement assembly.	Differential pressure (DP), flow, and closed-tank level measurements. This is the most common configuration.	DP/Gauge: up to 2000 psi
3051 In-Line	Compact, lightweight design with a single isolation diaphragm and single process connection. Installs directly onto pipes or vessels.	Gauge pressure, absolute pressure, and open-tank level measurement.	Gauge/Absolute: up to 20,000 psi

Within the In-Line family:

Within the Coplanar™ family:

Oil & Gas: Pipeline pressure monitoring, separator level control
Chemical & Petrochemical: Reactor pressure, distillation column level
Power Generation: Boiler drum level, steam pressure
Water & Wastewater: Pump suction pressure, tank level
Pulp & Paper: Digester pressure, stock flow
Food & Beverage: Sanitary pressure and level measurement (with appropriate seals)

The 3051 transmitter supports multiple communication protocols for seamless integration with control systems:

Protocol	Description
4–20 mA HART®	Most common, analog + digital communication
FOUNDATION™ Fieldbus	Digital bus for distributed control
Profibus® PA	Digital bus, widely used in Europe and process industries
WirelessHART®	Wireless version (Rosemount 3051S Wireless) for remote or hard-to-reach locations
