Rosemount™ 2051 Coplanar™ Pressure Transmitter

The Rosemount 2051 Coplanar Pressure Transmitter is industry-standard for differential and gage measurements. This safety-certified transmitter features a Local Operator Interface with easy-to-use menus and built-in configuration buttons, allowing you to easily commission the device. Engineered with the patented coplanar technology, this device offers installation flexibility for integrated flow or level solutions. With optional WirelessHART® technology, you can add measurement points fast, even in remote and hard-to reach-locations.

Pressure Sensor Technology

Pressure technology solutions include capacitive, piezoresistive and other sensors to provide essential process data in differential, gage and absolute pressure applications. These sensors measure pressure, level, flow and derivatives by physically responding to the changes in process pressure, converting the physical movement into an electrical signal.

CoplanarTransmitter

The Coplanar transmitter houses a capacitance sensor with patented Saturnsensing technology enhancing performance to deliver industry-leading accuracy and overpressure protection. The Coplanar configuration is easily integrated with a variety of manifolds, primary elements and remote seals. Configurations deliver performance and functionality for differential pressure, true gage or absolute pressure readings.

In-Line Transmitter

The Rosemount In-line Transmitter uses field-proven, piezoresistive sensor technology converting resistance into an electrical signal. In-line Transmitters connect directly to the process with a direct threaded connection, manifold or seal system solutions. This configuration is designed for accurate and reliable true gage or absolute pressure measurements.

Multivariable Transmitter

Multivariable Transmitters are engineered with multiple sensing elements in the same transmitter housing. An innovative design, this single device is capable of providing differential pressure, static pressure and process temperature measurements. Multivariable Transmitters are commonly used for mass flow and energy measurement applications.

Paine Sensor

Paine Sensors are available in a diaphragm or tube configurations. The diaphragm design consists of a wheatstone bridge with foil gages on the diaphragm with two legs in tension and two in compression and is typically used for pressures less than 5000 psi (345 bar). The tube-type sensor is designed with sets of strain wire wrapped around a pressurized tube and tied together to form a wheatstone bridge. They are generally used with pressures greater than 5000 psi (345 bar).
