P233A-4-PAC | Differential Pressure Switch, 50 to 400 Pa Range, < 0.3 Mbar Differential, SPDT, No accessories included | Johnson Controls

Int'l Diff'l Air Press Switch The Johnson Controls P233A-4-PAC is an international differential air pressure switch, designed to control air pressure within a specific range. It is commonly used in industrial and commercial applications, such as HVAC systems, to monitor and maintain air pressure levels. With its reliable performance and precise control, the Johnson Controls P233A-4-PAC ensures optimal system operation and efficiency. Key Features: * Differential pressure range: 0.25" to 10" w.c. * Adjustable set point and deadband * SPDT output contacts * UL listed * CSA certified Benefits: * Precisely controls air pressure within a specified range * Prevents over-pressurization and under-pressurization of systems * Improves system efficiency and performance * Ensures consistent air pressure for critical processes * Easy installation and maintenance Applications: * HVAC systems * Air handling units * Fan or blower control * Pressurization systems * Industrial machinery * Cleanrooms This switch senses a change in the (differential) pressure as the airflow changes. The (differential) pressure is applied to the two sides of a diaphragm in the control. The spring-loaded diaphragm moves and actuates the switch. The series P233A/F can also be used to detect small positive gauge pressure or to detect a vacuum.
