Rosemount™ 4051S Pressure Transmitter

The Rosemount 4051S Pressure Transmitter can be assembled with various components to enhance its functionality. You can integrate instrument manifolds like the Rosemount R305 Integral Manifold or Rosemount R306 In-Line Manifold for isolation and equalization, making maintenance and calibration easier. Diaphragm seal systems such as the Rosemount 1299 Diaphragm Seal System can be integrated into a single Rosemount 4051SLT Level Transmitter model number to allow for protection from harsh process conditions, ensuring accurate measurements.

Additionally, primary elements like orifice plates and annubar flow elements are ideal for flow measurement applications and can be specified on the Rosemount 4051S platform through dedicated flow meter model numbers including the Rosemount 4051SFC Compact Orifice Flow Meter, Rosemount 4051SFA Annubar Flow Meter and Rosemount 4051SFP Integral Orifice Flow Meter.​

Lead times vary based on your geographic location and your product configuration. For the most up to date lead-time, please use the Emerson.com product configurator or contact your local Emerson representative.

To order a Rosemount 4051S Pressure Transmitter, start by using Emerson’s website and online store, contacting your Emerson sales representative or contacting an authorized distributor. You will need to specify the requirements for the pressure measurement and any additional features required, such as Bluetooth® connectivity or advanced diagnostics. Consider the environmental conditions and process requirements to select the appropriate materials and configurations, like instrument manifolds or diaphragm seals. Once you've configured your transmitter, you can place your order online or through an Emerson sales representative.​

The pressure data from the Rosemount 4051S transmitter can be used to see how hard a pump is working by measuring the pressure at the inlet and outlet. This helps understand if the pump is using more energy than needed. By adjusting the pump speed instead of using valves to restrict flow, you can reduce wasted energy and run the pump more efficiently while avoiding problems like cavitation or excess pressure.

The diagnostic features of the Emerson Rosemount 4051S Pressure Transmitter can be used to continuously monitor the health and performance of both the pressure transmitter and the process. Built-in diagnostics can detect issues with the electrical loop, plugging in impulse lines or abnormal process conditions early, allowing maintenance teams to address problems before they cause failures. This proactive insight reduces unplanned downtime by preventing sudden equipment outages and lowers maintenance costs by enabling condition-based maintenance instead of routine or reactive repairs.
