Description
Cleveland Controls DDP-106-214 Air Pressure Sensing Switch
The Cleveland Controls DDP-106-214 is a dual-setpoint air pressure sensing switch engineered for precise differential pressure monitoring in commercial and industrial HVAC applications. Featuring two SPDT (Single Pole Double Throw) switching circuits, this unit provides independent contact changes on both increasing and decreasing pressure events, making it ideal for fan proving, filter monitoring, and airflow verification.
Key Features
- Dual SPDT switching action for independent control on rising and falling pressure
- Contacts change on decreasing pressure at 0.20″ w.c. — ideal for low-pressure fault detection
- Contacts change on increasing pressure at 1.35″ w.c. — confirms adequate airflow or filter loading
- Wide sensing range: 0.05″ ± 0.02″ to 2.0″ w.c.
- Broad voltage compatibility: 120V–277Vac
- Maximum inlet pressure rating: 1/2 PSI
- Compact design suitable for duct or equipment panel mounting
