GP1001-D Series differential pressure transmitter designed for industrial pressure measurement applications. It uses the world’s advance silicon pressure sensor technology and state of the airt encapsulation technology . it features self-diagnostic, field parameter adjustment, auto-zero and all industrial standard . It is composed of pressure transmitter and the welding installation level flange, which can measure liquid, gas or steam pressure as well as fluid density and level. Output options available include 4-20mA with HART protocol. 



The process pressure is transmitted to the mono-silicon pressure sensor through the isolation diaphragm and the filling liquid. When the force is applied, the Wheatstone bridge imbalance resistance value changes, and the current excitation is used to convert into a linear value voltage output with the differential pressure value.
