Rosemount 3051 Multivariable Differential Pressure Transmitter
1.General Description of Rosemount 3051
The Rosemount 3051 is a Differential Pressure Transmitter that measures pressure, temperature, and flow in a single device. Its Coplanar Pressure Transmitters design allows easy installation, reliable performance, and simple maintenance. Also called 3051 Emerson or Emerson Rosemount 3051, it gives accurate readings. It works well in harsh conditions like oil and gas, chemical processing, and water treatment.
The Rosemount 3051 level transmitter version enables precise level measurement, and the Rosemount 3051 configurator simplifies setup and diagnostics. Engineers build each Rosemount 3051 model to meet rigorous standards for pressure transmitters, coplanar pressure, and differential gauge applications.
