Rosemount 2051CD Differential Pressure Transmitter<\/h6>\n
Product Overview<\/span><\/h6>\n
\n

The Rosemount 2051CD series differential pressure transmitter is a Rosemount brand measuring common plane differential pressure transmitter under Emerson, with 5 pressure measurement ranges. Corresponding to 2051 respectively CD1A(\u201362.2 to 62.2 mbar),2051CD2A(\u2013623 to 623 mbar),2051CD3A(\u20132.5 to 2.5 bar),2051CD4A(\u201320.7 to 20.7 bar),2051CD5A(\u2013137.9 to 137.9 bar)\u3002<\/p>\n

The 2051 pressure transmitter series is specially designed for harsh industrial environments, covering the entire range from micro differential pressure to high differential pressure. The measurement accuracy can reach up to 0.05% of the range, and it has a 5-year calibration free long-term stability. It is widely used in industries such as petrochemicals, power, water treatment, food and medicine, metallurgy, etc. It is a benchmark equipment for differential pressure measurement in industrial automation control systems.<\/p>\n

\u00a0Rosemount 2051CD Core technological advantages<\/span><\/h6>\n
\n

1. Industry leading measurement performance<\/strong><\/p>\n

-The benchmark accuracy can reach up to \u00b1 0.05% of the range, with a range ratio of up to 100:1, maintaining high-precision measurement throughout the entire range
\n-5-year long-term stability \u2264 \u00b1 0.125% range upper limit, significantly reducing calibration frequency and maintenance costs<\/p>\n

2. Full protocol communication<\/strong><\/p>\n

-Standard 4-20mA HART protocol and support for Wireless HART \u2122\u3001 FOUNDATION \u2122 Multiple protocols including fieldbus, PROFIBUS PA, 1-5V low-power HART, etc
\n-Compatible with existing DCS\/PLC control systems, while supporting wireless upgrades and data migration for future digital factories
\n-Supports HART 5\/7 version on-site configuration, which can flexibly adapt to different versions of the system ecosystem
\n-The Rosemount 2051 series can support a relatively complete range of series, but the cost is higher<\/p>\n

3. Adaptation to food grade and highly corrosive environments<\/strong><\/p>\n

-The standard liquid receiving material for the Rosemount 2051<\/strong> series is 316L stainless steel, and special materials such as Hastelloy C-276, Monel, Tantalum, and gold-plated Monel can be selected
\n-Adapt to strong corrosive media such as strong acids, strong bases, and organic solvents to meet the special working conditions of industries such as chemical, pharmaceutical, and environmental protection,
\n-The filling liquid can be selected from silicone oil and inert halogenated hydrocarbon liquid, suitable for different scenarios such as high temperature, low temperature, and food hygiene grade. We also supply you with many dairy food companies from European countries, Italy, and Germany.
\n-The shell is made of 316L stainless steel to meet special working conditions. The following are actual photos of Rosemount 2051<\/strong> stainless steel liquid level transmitter<\/p>\n
