Barksdale CD2H-H18SS Pressure Switch

The Barksdale CD2H-H18SS is a dual-setpoint, housed diaphragm pressure switch designed for reliable pressure control in industrial fluid systems. It provides two independent SPDT switch outputs that actuate at user-adjustable pressures in the 0.4 to 18 psi range, making it suitable for monitoring and controlling pumps, compressors, and valve controls in compact piping setups. The pressure port is 1/4" NPT female, and the housed enclosure delivers protection consistent with a NEMA Type 4 (weather-resistant) rating, suitable for indoor or protected outdoor installations. Electrical ratings for the device include contacts rated up to 10 A at 125/250 VAC and 3 A at 480 VAC, depending on configuration, aligning with the CD2H family’s typical specifications for housed, dual-setpoint switches. The CD2H-H18SS belongs to Barksdale’s pressure-switch lineup and is engineered for repeatable actuation with diaphragm sensing, offering stable setpoints across varying pressure conditions. Common applications include fluid-handling circuits, pneumatic and hydraulic control loops, and safety interlocks where two pressure thresholds are required to manage stages of operation or interlocks between equipment. This model is identified by the H18SS designation (dual setpoints) within the CD2H family, providing a robust, industrial-grade solution for precise pressure-based control in demanding environments.
