    Hazardous Location Differential Pressure Switches for Air

    Image of Product. Front orientation. Differential Pressure Switches.
    With an explosion-proof enclosure that meets NEMA 7 and 9 standards for hazardous locations, these switches were tested and verified by UL for use where explosive gas or dust may be present. Often used with ovens, dryers, and HVAC systems, they can indicate a filter is clogged or help maintain a certain air pressure. These switches turn equipment on and off, activate automated controls, or signal alarms when the differential pressure reaches your setpoint. They are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on or from on to off.
    In addition to being UL listed, these switches are CE marked and FM approved, so they also meet European safety standards. They also are IP and NEMA rated for use outdoors and protect against dust and splashing water.
    When measuring pressure in ductwork, pair them with a static pressure probe.
