Product Description

Emerson Rosemount Original 1151 Differential Pressure Transmitter 

The Emerson Rosemount Original 1151 Differential Pressure Transmitter is a time-tested, high-performance solution designed to deliver precise and reliable pressure measurements in demanding industrial environments. Renowned for its durability and accuracy, the 1151 series has been a cornerstone of process control for decades, serving industries such as oil and gas, chemical processing, power generation, water treatment, and HVAC. Its robust design, combined with optional HART® digital communication, ensures seamless integration into both legacy and modern systems while maintaining exceptional performance.

Core Technical Performance The 1151 transmitter provides differential pressure measurement across an extensive range of 0–0.1 kPa to 0–41375 kPa (0–0.15 psi to 0–6000 psi), catering to low-, medium-, and high-pressure applications. Standard models offer ±0.25% of span accuracy, with high-accuracy variants achieving ±0.1% for critical processes. The transmitter supports 4–20 mA analog output or 4–20 mA + HART® 7 digital communication, enabling remote configuration, calibration, and diagnostics via tools like the Emerson Field Communicator. Powered by 10.5–42 V DC (loop-powered for 4–20 mA models), it operates reliably in ambient temperatures from -40°C to +85°C (-40°F to +185°F) and responds to process changes in under 2 milliseconds, with adjustable damping for stability.

Innovative Design and Durability The 1151 series features 316L Stainless Steel, Hastelloy C-276, Monel 400, or Tantalum wetted materials, ensuring compatibility with corrosive, abrasive, or high-temperature media. It is available with flanged (ANSI/DIN/JIS), threaded (NPT/BSP), or hygienic clamp-style connections, adhering to ASME B16.5/B16.47 and ISO 7005 standards. The IP66/IP67-rated aluminum or stainless steel enclosure protects against dust, moisture, and mechanical impacts, while its sensor design resists vibration (2g RMS) and shock (50g), ensuring long-term performance in extreme environments like offshore platforms, refineries, and chemical plants.

Advanced Communication and Diagnostics Equipped with HART® 7, smart variants of the 1151 enable bidirectional communication for real-time monitoring of sensor health, process anomalies, and predictive maintenance alerts.
