Dwyer Instruments DXW-11-153-3 Differential Pressure Switch NEMA 4X SPDT 1/4"

The Dwyer Instruments DXW-11-153-3 Differential Pressure Switch is used to measure the pressure variation in HVAC systems for efficiency and safety. It operates based on the principle of differential pressure between two points and switches on when a certain pressure level is attained to control equipment such as air handling units, filters or fans. It has an NEMA 4X enclosure rating, which makes it suitable to be used in harsh conditions. This switch type is single-pole, double-throw and it has 1/4 ”NPT connection which allows it to be used in various installations. They include accurate pressure measurement, protection of the system, and enhanced performance of HVAC systems.
