1. Product description:

　　The Rosemount 2051 family of pressure transmitters empowers you to measure pressure with confidence.The 2051 provides a reliable differential, gage, and absolute pressure measurement with a variety of output protocols, materials and process connections. Meet your pressure, level, andflow application needs with its flexible Coplanar™ platform so that you can lower project and ongoing maintenance costs.It create a new standard for pressure measurement technology.

2. Working principle

　　How it works: work, high and low pressure side of the isolation diaphragm and fill fluid is passed to the process pressure to the irrigation fluid-filled, then fill fluid pressure delivered to the sensing diaphragm of the sensor center. The sensing diaphragm is a tension of the elastic element, its displacement with the pressure change (for the GP gauge pressure transmitter, the atmospheric pressure as imposed in the low voltage side of the sensing diaphragm). AP absolute pressure transmitter, low pressure side is always to maintain a reference pressure. The maximum displacement of the sensing diaphragm to 0.004 in. (0.1 mm), proportional to the pressure and displacement. Both sides of the capacitor plates detect the position of the sensing diaphragm. The difference between the capacitance between the sensing diaphragm and the capacitor plates is converted to the corresponding current, voltage, or digital HART (Highway Addressable Remote Transmitter output signal of the data highway).

3. Application of Rosemount 2051 pressure transmitter:

　　The new  Rosemount 2051C pressure transmitter performance indicators to ensure the accuracy and stability in different conditions. A flexible CoPlanarTM platform design not only provide the best solution for your current application needs PlantWeb factory control network and fieldbus technology can meet your technical requirements in the future.
