Product Name: Compact Differential Pressure Transmitter
Model: YD322-IN

YD322-IN compact differential pressure transmitter is suitable for differential pressure measurement of liquids and gases.

working principle:
Differential pressure transmitter is a typical self balancing detection instrument that uses the working principle of negative feedback to overcome the influence of adverse factors such as component materials and processing technology.
As the name suggests, the result measured by a differential pressure transmitter is the pressure difference, that is, △ P=ρ g △ h. 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 proportional to △ P. As long as the Δ P value is accurately detected and proportional to the height Δ h, the pressure detected remains constant even when the volume of the oil expands or shrinks and the actual liquid level rises or falls during temperature changes. If the user needs to display the actual liquid level, medium temperature compensation can also be introduced to solve the problem.
