Differential pressure is a crucial concept to grasp when considering the purchase of a differential pressure gauge. This section provides a brief description to help buyers develop a foundational understanding of this important measurement parameter.
Differential pressure refers to the difference in pressure between two distinct points in a system. It is often used to measure and monitor fluid flow, air velocity, filter conditions, and other critical variables in various industrial applications.
Buyers should be aware that differential pressure is typically represented as the numerical value between two pressure points, expressed in units such as pascals (Pa), pounds per square inch (psi), inches of water column (inWC), or millibars (mbar). Understanding the unit of measurement and its relevance to your specific application is crucial in selecting an appropriate differential pressure gauge.
Moreover, it is essential to comprehend the relationship between positive and negative differential pressure. Positive differential pressure occurs when the pressure at one point is higher than the pressure at another point, while negative differential pressure indicates the opposite—a lower pressure at one point compared to the other. Different types of systems and processes may require the measurement of either positive or negative differential pressure, or both.
By gaining a solid understanding of differential pressure, buyers can make informed decisions when choosing a differential pressure gauge that meets the specific requirements of their application.
