Differential Pressure Gauges

Differential pressure gauges are designed to measure the difference between two pressures. Unlike standard pressure gauges which measure the pressure at a single point, differential gauges measure the pressure at two points, such as on either side of a filter, and display the pressure difference between those points. Differential pressure gauges are commonly used to monitor filter contamination, measure level in closed vessels, overpressure measurement in clean rooms, and for monitoring pressure in pumping plants.
