Emerson Rosemount 3051GP Differential Pressure Transmitter
The Emerson Rosemount 3051GP Differential Pressure Transmitter is a high-performance industrial instrument engineered to deliver precise, reliable, and stable pressure measurements in demanding process environments. As part of Emerson's renowned 3051 Series, the 3051GP combines advanced sensor technology with robust design, making it a trusted solution for critical applications across oil and gas, chemical, power generation, water treatment, and other industries. Its versatility, durability, and compatibility with modern communication protocols position it as a cornerstone for process optimization, safety, and efficiency.
At the heart of the 3051GP is a patented capacitive silicon resonant sensor that ensures exceptional accuracy (±0.075% of URL) and long-term stability (<0.1% URL/year). This technology enables the transmitter to maintain precision even in harsh conditions, such as fluctuating temperatures (-40°C to +125°C) or exposure to corrosive media. The sensor's design minimizes drift, reducing the need for frequent recalibration and lowering lifecycle costs. Additionally, the transmitter supports multivariable measurement in select models, allowing simultaneous monitoring of differential pressure, static pressure, and temperature-enabling real-time flow calculations and process insights.
The 3051GP is designed for seamless integration into diverse industrial systems. It offers multiple output options, including standard 4-20 mA analog signals, HART 7, FOUNDATION Fieldbus, and WirelessHART protocols. This flexibility ensures compatibility with both legacy control systems and modern digital infrastructures, supporting Industry 4.0 initiatives like predictive maintenance and remote monitoring. The transmitter's rugged construction features materials such as 316 stainless steel, Alloy C-276, and Tantalum, ensuring resistance to aggressive chemicals, high pressures (up to 16,000 psi overpressure limit), and mechanical stress. Process connections include threaded, flanged, and coplanar options to adapt to varied piping and vessel configurations.
Safety and compliance are integral to the 3051GP's design. It meets global standards such as ATEX, IECEx, FM, and SIL 2/3 certifications, making it suitable for hazardous and safety-critical environments. Its advanced diagnostics capabilities, including self-checks and partial stroke testing, enhance operational safety by identifying potential failures before they disrupt processes. The transmitter also adheres to NACE MR0173 for sour service applications, expanding its utility in oil and gas sectors where hydrogen sulfide exposure is a concern.
Installation and maintenance are simplified through user-friendly features. The transmitter's adjustable LCD display (optional) allows local monitoring of process variables, while remote configuration via AMS Device Manager or field communicators reduces downtime. Its compact, lightweight design (4.5-6.5 kg) and 360° rotating housing facilitate easy mounting in confined spaces. Furthermore, the 3051GP's low power consumption (10.5-42 V DC) and compatibility with solar or battery-powered wireless systems make it ideal for remote or energy-constrained locations.
In summary, the Rosemount 3051GP Differential Pressure Transmitter is a premium solution for industries requiring unmatched measurement accuracy, environmental resilience, and digital interoperability. Whether used for liquid level monitoring, gas flow control, or filter efficiency tracking, it empowers operators to enhance process efficiency, reduce downtime, and ensure compliance with evolving safety and environmental regulations. By combining decades of Emerson's engineering expertise with cutting-edge innovation, the 3051GP stands as a benchmark for performance in the world of industrial instrumentation.
