Rosemount E1151 Pressure Transmitter with Manifold

The Rosemount 1151 Pressure Transmitter is a rugged, industry-proven smart pressure transmitter designed for accurate measurement of differential pressure, gauge pressure, liquid level, flow, and process pressure in demanding industrial environments. Supplied with a valve manifold assembly, this transmitter allows convenient isolation, equalization, calibration, and maintenance without process shutdown. The Rosemount 1151 series became one of the most widely installed pressure transmitters in the oil & gas, chemical, power generation, and process industries due to its reliability, stability, and long service life.

Function

The Rosemount 1151 measures pressure by sensing the differential force acting across an isolation diaphragm and converting this into a proportional 4–20 mA output signal. When installed across an orifice plate, venturi, or flow element, it can accurately measure flow. It can also be used for tank level measurement, filter monitoring, pump performance monitoring, and general process pressure applications. The included manifold simplifies commissioning, calibration, and maintenance operations.
