Over 10 Million Global Installations, Defining the Gold Standard for Pressure Measurement: The Rosemount 3051 Series Dif

In the field of pressure measurement, one name has become synonymous with reliability, precision, and innovation—the Rosemount 3051 series. As the flagship product of Emerson Process Management, over 10 million 3051 transmitters have been deployed across various harsh industrial environments worldwide, with their exceptional performance standing the test of time. Xi'an Xin Yi Instrument Technology Co., Ltd. presents this legendary instrument—the original Rosemount 3051 series differential pressure/pressure transmitter. This instrument, embodying decades of field wisdom, delivers a 10-year installation stability, a 150:1 range ratio, a 0.04% span accuracy, and robust SIL 2/3 safety certification. It provides a globally proven "gold standard" solution for pressure, level, and flow measurement in industries such as oil, chemicals, power, and metallurgy.

• 1,10-year ultra-long stability with extremely low maintenance costs
  The core advantage of the Rosemount 3051 lies in its exceptional long-term stability. Thanks to its precision sensor design and advanced manufacturing processes, the transmitter ensures outstanding performance metrics over a 10-year installation and operational cycle, significantly reducing the need for regular calibration and downtime maintenance. This provides extremely high reliability and very low total cost of ownership for continuous production processes.
• 2.,150:1 turndown ratio, flexible and worry-free application
  The product boasts a measurement range ratio of up to 150:1, enabling a single transmitter to flexibly cover an extremely wide measurement span. Whether it's minute flow fluctuations or significant level variations, the 3051 can accurately capture them, greatly simplifying selection and inventory management while flexibly adapting to changes in different working conditions and application scenarios.
• 3.,Enhanced Diagnostic Functions and Safety Integrity Levels
  The 3051 series features robust built-in diagnostic functions, such as loop integrity diagnostics, enabling proactive monitoring of electrical circuit integrity to promptly identify potential issues and minimize unplanned downtime. Additionally, this series has been certified by third-party independent institutions, complying with the IEC 61508 safety standard and achieving up to SIL 2/3 levels, ensuring safe and reliable application in critical safety instrument function circuits like emergency shutdown systems.
• 4.,Multiple Communication Protocols with Perfect Compatibility
  Supports mainstream industrial communication protocols including 4-20mA HART, wireless HART, FOUNDATION Fieldbus, Profibus, etc., ensuring seamless integration of the transmitter into any newly built or existing control system (such as DCS, PLC). Combined with the local operation interface, on-site debugging and information retrieval are equally convenient.

Solid parameters create legendary quality:

• Oil and gas: flow measurement of oil/gas pipelines, level control of separators, and monitoring of wellhead pressure.
• Chemical and Fine Chemicals: Reactor pressure/liquid level, distillation tower differential pressure monitoring, pump outlet filter blockage alarm.
• Electricity and Energy: Measurement of boiler drum water level, main steam flow rate, feedwater system pressure, and primary/secondary air pressure.
• Metallurgy and papermaking: differential pressure measurement related to blast furnace gas pressure, pulp liquid level, and black liquor concentration.
