    Hazardous Location Differential Pressure Switches for Liquids

    Image of Product. Front orientation. Differential Pressure Switches. Hazardous Location Differential Pressure Switches for Liquids.
    Tested and verified by UL and C-UL for use where explosive dust or gas are present, these switches have an explosion-proof enclosure that meets NEMA 7 and 9 standards for hazardous locations. They are often used to indicate a filter is clogged in a pump or cooling system. 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.
    In addition to being UL and C-UL listed, these switches are CE marked, so they also meet European safety standards. All switches are IP and NEMA rated for use outdoors and to protect against some corrosion, dust, and washdowns.
