Description
Differential pressure (pressure) transmitter is a typical self-balancing instrumentation, which uses the working principle of negative feedback to overcome the components of materials, processing and other unfavorable factors.
As the name implies differential pressure transmitter measured the result is the pressure difference, that is, P = ρg h. However, since the tank is often cylindrical, the area S of the cross-section circle is constant. Then, the gravity G = P · S = ρg h · S, S is constant, and G is proportional to P. That is, as long as the P value is accurately detected, it is proportional to the height Δh. When the temperature changes, the detected pressure is always maintained although the oil volume expands or contracts, and the actual liquid level increases or decreases. If you need to display the actual level, you can also introduce media temperature compensation to be resolved.
