Differential pressure

Differential pressure switches are perfect for measuring and monitoring the positive, negative, and differential pressure of air and gaseous, non-aggressive media in air ducts and air supply and exhaust units. They can also be used when monitoring filters, as differential pressure provides an indication of the contamination of a filter. 

If you can't find your differential pressure switch, simply contact us and we'll be happy to help! The items displayed below are only a few from our large selection.
