Rosemount 1151DP transmitter

Rosemount 1151DP transmitter  buyer


Specification :

1151 pressure transmitter of two measured media pressure leads to high and two low-pressure chamber acting on the δ element (sensor) of both sides of the diaphragm through the diaphragm and filling liquid mass within the element δ to pre-tensioned membrane electrode and insulator on both sides of the measuring sides wax sheet, measuring the components of a capacitor is measured in the absence of pressure through the pressure equalization diaphragm or two in the middle position, the two sides of the capacitance of the capacitor equal pressure on both sides when inconsistent, resulting in a displacement measuring diaphragm, which is proportional to the amount of displacement and the pressure difference, so both sides of the capacitors will not wait, by detecting amplified and converted into a two-wire current signal 4-2OmA
