Product Features/Benefits

Model 522 Differential Pressure Gauge & Switch is a compact, weather resistant gauge for challenging DP Applications and installations when quickly identifying critical differential pressures are required. It is suitable for use in outdoor and “Hose Down” applications. The Rolling Diaphragm Sensing Element isolates the high and low side. Example: Used to determining the state of an in-line filter. Filtration systems require monitoring to maintain a level of performance specified by the manufacturer for the continued expectations of the end user. Colored bands allow you to quickly identify pressure drop across element. Divided into three sections, each clearly marked for ease of understanding. Model 522 is suited for filter applications, line loss, valve drop, and many other differential pressure applications where a simple indicator is needed. Used to indicate critical pressure drops or when to change or clean a filter. Model 522 is suited for use in Air, Gas, Dissimilar fluids, Wet Gas and process fluids with particulates present. Available with or without DIN Plug type switch
