Rosemount 3051TG Pressure Transmitter supplier

3051TG transmitter Features:

Rosemount's Model 3051T transmitter combines sensor, electronics and single isolation diaphragm design to achieve

 gauge and absolute pressure measurements from 0.3 to 10,000 psi.



Working principle of 3051T pressure transmitter: 

When working, the isolation diaphragm and filling liquid on the high and low pressure sides transfer the process pressure 

to the filling liquid, and then the filling liquid transfers the pressure to the sensing diaphragm in the center of the sensor. 

The 3051 Pressure Transmitter Sensing Diaphragm is a tensioned elastic element whose displacement varies with pressure

(for a 3051 GP pressure transmitter, atmospheric pressure is applied to the low pressure side of the sensing diaphragm).

The 3051AP absolute pressure transmitter maintains a reference pressure on the low pressure side. The maximum displacement

of the sensing diaphragm is 0.004 inches (0.1 mm) and the amount of 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 capacitor plate is converted to the corresponding current, voltage or digital HART (High Speed Addressable Remote Transmitter 

Data Highway) output signal 4-20mA with digital signal based on HART protocol.
