Pressure measurement solution for challenging industrial installations

30 November 2015

The Rosemount 3051S pressure transmitter, from Emerson Process Management, has been enhanced to allow new measurement possibilities in high process temperatures or changing ambient conditions.

The new Rosemount 3051S Thermal Range Expander, with the patented UltraTherm 805 oil fill fluid, is said to enable pressure measurements by direct-mounting a diaphragm seal system to processes that reach up to 410°C without requiring impulse piping or heat tracing used in traditional connection technology. In applications where ambient temperatures drop below ideal operating conditions, system response time becomes slow, resulting in delayed process pressure readings. Traditionally, this problem is solved by using heat tracing which is costly, maintenance intensive, and difficult to install. The new thermal range expander dual fill fluid seal is said to allow the Rosemount 3051S to  continue to reliably measure pressure at high process and low ambient temperatures.

The 3051S Electronic Remote Sensors (ERS) system now has safety certification. The ERS System calculates differential pressure through a digital architecture – and is now suitable for SIL 2 and 3 applications. The ERS system has solved the  problems associated with installing and maintaining traditional mechanical systems  by replacing filled capillaries with a digital connection, providing a stable and reliable measurement in safety applications. This solution is said to deliver improved performance and response time, and helps end users eliminate mechanical DP level systems.

Finally, the new Rosemount 3051S High Static Differential Pressure Transmitter provides reliable flow measurement in high-pressure applications with capabilities up to 1034 bar. Operators need to continually monitor equipment integrity and stability in order to prevent failures, safety hazards and decreased production. In industries such as offshore and onshore oil and gas and power generation it is critical that instrumentation be robust enough to provide accurate measurements on a consistent basis. The transmitter’s SuperModule platform and coplanar design reduce potential leak points by 50% compared to traditional designs.
