 Compact gas differential pressure transmitter


Yd322-in compact differential pressure transmitter is suitable for liquid and gas differential pressure measurement.Differential pressure (pressure) transmitter is a typical self-balancing measuring instrument. It USES the principle of negative feedback to overcome the influence of adverse factors such as component materials and processing technology.As the name implies, the results measured by the differential pressure transmitter were pressure differences, i.e.As the oil tank is usually cylindrical, the area S of its section circle is constant. Therefore, gravity G= pn ·S= G imperceptibly, S is constant, and G is in direct proportion to pn.That as long as accurately detect the delta P value, is proportional to the height delta h, when the temperature changes, while the oil volume expansion or narrow, the actual level higher or lower, detected by the pressure is always remains the same.If the user needs to display the actual liquid level, the medium temperature compensation can also be introduced to solve the problem.
