Differential Pressure Switches for Air
 |
Connects to Pipe |
Often used with ovens, dryers, and HVAC systems, these switches detect small differences in air pressure to indicate a filter is clogged or help you maintain a certain air pressure. When the differential pressure reaches your setpoint, these switches can turn equipment on and off, activate automated controls, or signal alarms. They are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on or from on to off. All meet at least one safety standard.
When measuring pressure in ductwork, pair them with a static pressure probe.
