Rosemount 3051L Transmitter Type
Product Details


3051 pressure transmitter is marketed as a core product in all rosemont products. Support and preferential policies in all aspects take precedence over other products.

When it works, the isolation membrane on the side of high and low pressure and the filling liquid transfer the process pressure to the filling liquid, and then the filling liquid transfers the pressure to the sensor diaphragm in the center of the sensor. The sensor diaphragm is a tensioned elastic element whose displacement varies with the pressure applied (in the case of a GP pressure transmitter, atmospheric pressure is the same as on the low-pressure side of the sensing diaphragm). AP pressure converter, where low pressure side always maintains a reference pressure. The zui large displacement of the sensing diaphragm is 0.004 inches (0.1 mm), and the displacement is proportional to the pressure. The capacitance plate on both sides detects the position of the sensing diaphragm. The difference between the capacitance between the sensor diaphragm and the capacitor plate is converted into the corresponding current, voltage or digital HART (high speed addressable remote transmitter data road) output signal.
