By knowing the pressure before and after the filter, you can determine if it is clogged. That pressure sensor can be used to control a valve to keep steam pressure at a constant level.Īnother common but lesser known use is to monitor the level of a liquid in a tank.įilter clogs are a common use of differential pressure monitoring.
Pressure sensors are commonly used to monitor pressures in different processes.Ī common thing to monitor is steam pressure. its not only reasonable for a vinyl master to be cut from a digital file. Gauge pressure is measured against the atmospheric pressure, absolute is measured against a vacuum, and the differential pressure is the difference between two pressures. Now imagine trying to maintain that speed on a tightly winding mountain road. These sensors commonly measure Gauge Pressure, Absolute Pressure, and Differential Pressure. This is why many sensors are referred to as transmitters.
Pressure sensors convert the pressure into an electrical signal that can be transmitted and displayed. To determine the velocity, an anemometer detects change in some physical property of the fluid or the effect of the fluid on a mechanical device inserted into the flow. The standard units are the Pascal, Bar, and PSI or pounds per square inch. An anemometer is an instrument used to measure the speed or velocity of gases either in a contained flow, such as airflow in a duct, or in unconfined flows, such as atmospheric wind. Pressure is an expression of force exerted on a surface per unit area.
