Rosemount 2051 Pressure Transmitter

Apr 25, 2016

Rosemount 2051CD  Pressure Transmitter 


Basic Information :

2051 Pressure transmitters are mainly capacitive pressure transmitter and diffused silicon pressure transmitter, ceramic  pressure transmitter strain.Pressure range can be divided according to the general pressure transmitter (0.001MPa ~ 35MPa) and a differential pressure transmitter (0 ~ 1.5kPa), three kinds of negative pressure transmitter


The main role of the pressure transmitter pressure signals to the electronic device, and then the computer displays the pressure of the principle generally: the mechanical signal into a current pressure of this pressure (4-20mA) Such electronic signal pressure and voltage or current size of the linear relationship is generally positive relationship. Therefore, the output voltage or current transducer with pressure increases thereby obtain two kinds of pressure measured media pressure and a voltage or current relationship leads to high pressure transmitter, two low pressure chamber , low pressure chamber with atmospheric pressure or vacuum acting on the δ yuan (ie, sensor) of both sides of the diaphragm, is transferred to the measurement on both sides of the diaphragm and filling liquid through the spacer element inside.


Pressure transmitteris a measuring electrode on both sides of the diaphragm and the insulating sheet on the various components of a capacitor. When both sides of the pressure is inconsistent, resulting in a displacement measuring diaphragm, which is proportional to the amount of displacement and the pressure difference, so both sides of the electric capacity will not wait, by shaking and demodulation links.


Output

Two-wire 4-20mA, user selectable for linear or square root output. Digital process variable superimposed on 4-20 mA signal, available to any host that conforms to HART protocol.


2051

Digital communications based on HART Revision 5 protocol.


2051 with selectable HART

The 2051 with Selectable HART comes with Selectable HART Revisions. Digital communications based on HART Revision 5 (default) or Revision 7 (option code HR7) protocol can be selected. The HART revision can be switched in the field using any HART based
