Description
The Cleveland Controls DDP-106-272 is a dual-action air pressure sensing switch engineered for precise differential pressure monitoring in commercial and industrial HVAC applications. Featuring two SPDT (Single Pole Double Throw) contacts, this switch provides independent switching actions on both increasing and decreasing pressure events, making it ideal for fan proving, filter monitoring, and airflow verification systems.
Key Features
- Dual SPDT contact configuration for independent switching on rising and falling pressure
- Changes contacts on decreasing pressure at .20″ w.c. setpoint
- Changes contacts on increasing pressure at 1.40″ w.c. setpoint
- Wide sensing range of .05″ ± .02″ to 2″ w.c.
- Broad voltage compatibility: 120V–277Vac
- Maximum pressure rating: 1/2 PSI
- Suitable for fan proving, filter status, and airflow monitoring
