Differential pressure measurement in industrial applications
A detailed look at the world of differential pressure measurement.
How do differential pressure sensors work, and how do they differ from other sensor types? Gauge pressure and absolute pressure sensors have defined reference points for measuring pressure differences (for absolute pressure: absolute vacuum, for gauge pressure: atmospheric pressure). In contrast, differential pressure sensors measure the difference between two pressures without defining a reference point. Differential pressure sensors can be made in various structures, but one feature of KELLER Pressure's products is that there is a type that can use liquid in both ports (e.g., model PD-33X). They can measure differential pressure with high resolution. There are also sensors that use two absolute pressure measurement cells to measure two pressures and determine the differential pressure through electronic circuits (model PD-39X). This structure is particularly suitable for high-pressure applications. Typical applications of differential pressure sensors: 1. Flow measurement There are several methods for measuring flow, but one common method is differential pressure measurement through an orifice plate. 2. Level measurement of liquefied gas tanks Liquefaction reduces volume, allowing for transportation and storage. Why is differential pressure measurement suitable for this water level measurement?
