The Rosemount 3051CD Differential Pressure transmitter is the smart differential pressure transmitter in the Rosemount Transmitter. The Rosemount 3051 pressure transmitter offers unmatched operational performance, flexible CoPlanarTM platform, and can be upgraded. The performance of the new Rosemount 3051 transmitter guarantees accuracy and stability under different working conditions.

Working principle:

During operation, the isolation diaphragm and the filling fluid on the high and low pressure sides transmit process pressure to the filling fluid, which then transfers the pressure to the sensing diaphragm in the center of the sensor. The sensing diaphragm is a tensioning elastic element whose displacement varies with the pressure applied (for a GP table pressure transmitter, atmospheric pressure is applied as on the low pressure side of the sensing diaphragm). AP absolute pressure transmitter, low pressure side always maintain a reference pressure. The maximum displacement of the sensing diaphragm is 0.004 inches (0.1 mm), and the displacement is proportional to the pressure. Capacitive plates on both sides detect the position of the sensing diaphragm. The capacitance difference between the sensing diaphragm and the capacitor plate is converted to the corresponding current, voltage or digital HART (High Speed Addressable remote Transmitter Data Highway) output signal.
