Rosemount 2051 with Remote Seal System

The Rosemount 2051 Pressure Transmitter with Remote Seal System is the solution of choice for Saudi Arabia's high-temperature, viscous, and corrosive process measurement applications where direct process connection to the transmitter is impractical or unsafe. The capillary-connected diaphragm seal isolates the transmitter from Saudi Aramco's corrosive sour crude and hydrogen sulfide-laden process streams, while the oil-filled capillary transmits the pressure signal to the transmitter mounted at a safe distance. ARAMCO SAES-I-010 specifications call for remote seal systems on process temperatures above 121°C and for hydrogen sulfide service, making the 2051CF essential for Saudi Aramco Abqaiq gas processing and SABIC ethylene cracker column pressure measurement.

The remote seal's fill fluid selection is critical for Saudi Arabia's operating conditions — silicone fill fluid for high-temperature steam measurement at SEC power plants, glycerin fill for low-temperature applications, and high-temperature Neobee fill for food-grade polymer applications at SABIC polyolefin plants. Coplanar flange mounting eliminates the three-valve manifold required for conventional transmitters, simplifying installation on Saudi Aramco's crowded column skids. The transmitter's 16-bit sensor ADC and sigma-delta electronics maintain ±0.075% accuracy despite the fill fluid temperature coefficient effects inherent in remote seal systems.

For Saudi Aramco sulfur processing facilities at Abqaiq and Hawiyah, tantalum-coated diaphragms resist polysulfide corrosion that attacks standard stainless steel seals. Hastelloy C-276 wetted parts serve SABIC's hydrochloric acid and caustic process streams without corrosion-induced calibration drift. The 2051's proven platform with over 10 million units installed globally means calibration technicians at Saudi Aramco instrument shops are familiar with its maintenance requirements, reducing mean time to repair.

Razz Middle East stocks the full 2051 remote seal system range including extended diaphragm seals for jacketed pipe applications, sanitary flanged seals for SABIC polymer applications, and all capillary fill fluid variants. Our Dammam applications team sizes remote seal systems for specific Saudi Aramco process conditions, calculating fill fluid temperature correction factors and capillary length limitations for each application.
