Rosemount working principle: when working, the diaphragm and filling fluid on the high and low pressure sides transfer the
process pressure to the filling fluid, and then the filling fluid transfers the pressure to the sensor diaphragm of the sensor. The sensing diaphragm is a tensioned elastic element whose displacement changes with the pressure applied (for a GP gauge pressure transmitter, the atmospheric pressure is the same as applied to the low pressure side of the sensing diaphragm). AP pressure transmitter maintains a reference pressure on the low pressure side. The displacement of the sensing diaphragm is 4 inches (1 mm), and the displacement is proportional to the pressure. The capacitive plates on both sides detect the position of the sensing diaphragm. The difference in capacitance between the sensing diaphragm and the capacitive plate is converted into the corresponding current, voltage or digital HART (Addressable Remote Transmitter Data Highway) output signal.
The accuracy and stability of the performance index of the new Rosemount 351CD under different working conditions. The flexible and variable CoPlanarTM platform design not only provides solutions for your current application requirements, but also fulfills your future requirements through the PlantWeb factory control network and fieldbus.
