The Rosemount 3051S High Static DP Transmitter is part of Emerson's Rosemount 3051S pressure instrumentation platform. It is engineered for applications where conventional differential pressure transmitters may not withstand the high static pressures present in the process line.
Its compact SuperModule™ design combines high static pressure capability with reliable differential pressure measurement. The transmitter uses a coned-and-threaded direct process connection for high-pressure service and supports compatible communication and diagnostic options for integration into industrial control systems.
