DGP037 pressure transmitter

The DGP differential pressure transmitter adopts single crystal silicon technology pressure sensor. The single crystal silicon pressure sensor is located on the top of the metal body, away from the medium contact surface, achieving mechanical and thermal isolation. The high-strength electrical insulation between the glass sintered sensor lead and the metal substrate improves the flexibility and transient voltage protection ability of the electronic circuit, which can cope with complex chemical occasions and mechanical loads. At the same time, it has strong anti electromagnetic interference ability and is suitable for pressure measurement applications in harsh process industrial environments. Measurement range from 2kpa to 10Mpa

As the name suggests, the result measured by a differential pressure transmitter is the pressure difference, that is, △ P=ρ g △ h. However, since oil tanks are often cylindrical, the area S of their cross-sectional circle remains constant. Therefore, gravity G=△ P · S=ρ g △ h · S, S remains constant, and G is inversely proportional to △ P. As long as the Δ P value is accurately detected, it is inversely proportional to the liquid level height h and directly proportional to the height difference Δ h. When the temperature changes, although the volume of the oil expands or shrinks, the actual liquid level increases or decreases, the detected pressure remains constant. If the user needs to display the actual liquid level, medium temperature compensation can also be introduced to solve the problem
