1. General Introduction
Rosemount 3051C Coplanar Pressure Transmitters are the industry standard for differential, gage, and absolute pressure measurement. The coplanar platform enables seamless integration with manifolds, flow, and level solutions. It offers up to 5-year limited warranty, range down capability up to 150:1, support various communication protocol such as 4-20 mA HART, WirelessHART®, FOUNDATION fieldbus, Profibus, 1-5 V Low Power HART and etc.
Over 10 million Rosemount 3051 devices installed globally, providing reliable pressure readings in harsh environments, patented coplanar technology allows for direct mounting to multiple measurement applications, fully-assembled pressure, level and flow solutions arrive ready-to-install for improved reliability and performance, complete pressure assemblies are leak-tested and calibrated to reduce leak points up to 70% and simplify installation, 10-year installed stability and 150:1 range down produce reliable measurements and wide application flexibility, Local Operator Interface (LOI) enables quick commissioning and provides easy access to process and device information, SIL 2/3 certified to IEC 61508 (via 3rd party) and prior-use certificate of FMEDA data for safety installations
