GP-1001 a digital 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 .The GP1001 pressure transmitter is capable of gauge &absolute pressure measurement. it features self-diagnostic, field parameter adjustment, auto-zero and all industrial standard capabilities with half the price. 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 GP1001 pressure transmitter offers so many options that it can be configured for any application.

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.
