Description

1、 Product feature

　　The Rosemount 3051 pressure transmitter combines advanced technology with the versatile Coplanar ™ process connection to create a new standard in pressure measurement technology. Even under the most demanding conditions, the performance specifications of the Rosemount 3051 pressure transmitter provide unmatched long-term stability and reliability.

　　The Rosemount 3051 pressure transmitter is capable of differential, gage, or absolute pressure measurement. Utilizing advanced capacitance sensor technology (piezoresistive sensors for absolute pressure models) the Rosemount 3051C smart pressure transmitter is accurate up to ±0.04% resulting in total operating performance, the true measure of "real-world" transmitter performance, of ±0.15%. Additionally, the Rosemount 3051 pressure transmitter has an installed five-year stability of ±0.125% demonstrating the ability to maintain performance over a five year period under the most demanding process conditions. The high accuracy and stability of the 3051C equates to reduced variability, lower operating and maintenance costs, and improved plant safety.

　　The Rosemount 3051C smart pressure transmitter can utilize either traditional flanges or Rosemount's versatile Coplanar ™ platform designed to enable the best process connection for pressure, flow, and level applications. Right out of the box, the solution arrives factory calibrated, pressure-tested, and ready to install. The Rosemount 3051C smart pressure transmitter is also available in a number of materials and a wide range of hazardous area certifications are available

2、Product application

　　The performance parameters of new 3051C could ensure the accuracy and reliability in different working condition. Flexible platform design of Coplanar ™ not only provide best program for your current application requirement,but also meet your future technical requests through the PlantWeb factory control network and onsite field bus technology.

3、Technical data

　　Performance: 0.075% accuracy, 100:1 turndown ratio

　　Gap: calibration range from 0.1inH2O to 2000psi

　　Gauge pressure: calibration range from 2.5inH20 to 2000psi

　　Absolute pressure: calibration range from 0.167psia to 4000psia

　　Rugged compact design and light weight, easy to install

　　Composite scale (only CD, CG), measurable negative

　　Process isolation diaphragm: stainless steel, Kazakhstan type alloy, tantalum Mundell (only CD, CG) and

　　Mongolia on behalf of the gold-plated
