1. Product Overview:             Rosemount 2051tg pressure transmitter and Rosemount 2051ta absolute pressure transmitter integrate sensor, electronic technology and single isolation diaphragm design, and realize the calibration range of gauge pressure and absolute pressure measurement from 0.3 to 10000 psi. Working principle of Rosemount 2051tg pressure transmitter: during operation, the isolation diaphragm and filling liquid at the high and low pressure sides transmit the process pressure to the filling liquid, and then the filling liquid transmits the pressure to the sensing diaphragm in the center of the sensor. The sensing diaphragm of Rosemount 2051 pressure transmitter is a tensioned elastic element whose displacement varies with the pressure (for 2051gp pressure transmitter, atmospheric pressure is applied to the low pressure side of the sensing diaphragm as well). For Rosemount 2051ap absolute pressure transmitter, a reference pressure is always maintained on the low-pressure side. The maximum displacement of the sensing diaphragm is 0.004 inch (0.1 mm) and is proportional to the pressure. The capacitance 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.            II.
