HVAC pressure sensors are used to monitor the pressure within heating, ventilation, and air conditioning systems.

If differential pressure across the filter exceeds the switch’s setting, the switch will trigger and an “off normal” signal will be sent to the BAS. Commonly, the BAS will monitor that binary input, ...

Differential pressure switches have two pressure ports, a low pressure and a high-pressure side. The low pressure and high-pressure fluids act on the same sensing diaphragm.

Differential pressure ranges are selectable from 0 to 25 in. H2O to 0 to 100 psid, with full-scale accuracies of 5%. The miniature gages come with either piston or diaphragm sensors.

The DDS-Series differential pressure switch is designed to sense low differential pressures between high-pressure sources. It can control differential pressures from 0/6 to 0/150 inches of water on ...
