Differential Pressure Switches for Liquids
 |
Detect the difference in pressure between two points. For instance, these switches can indicate a filter is clogged in a pump or cooling system. When the differential pressure reaches your setpoint, they 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.
NEMA 4X Enclosure Rating—NEMA 4X rated switches can be used in dirty and wet areas exposed to washdowns and weather. They also have increased protection against corrosion, similar to 304 stainless steel.
NEMA 13 Enclosure Rating— NEMA 13 rated switches can be used in dirty, wet, and oily areas.
IP66 Enclosure Rating— IP66 rated switches protect against dust and washdowns.
