Product Description
The SG28A3 is a differential pressure switch that monitors pressure differential across filter elements in aircraft hydraulic, fuel, and pneumatic systems. When pressure drop exceeds a preset threshold—typically indicating filter clogging—the switch trips an electrical contact to alert maintenance crews or trigger automatic bypass functions. Commonly installed on hydraulic return filter housings, this switch prevents system damage from blocked elements.
Installation follows the aircraft maintenance manual and component CMM specifications. Verify setpoint calibration and electrical continuity during functional testing before flight operations.
Please note: Product descriptions are provided for informational purposes. Always refer to your aircraft's Illustrated Parts Catalog (IPC) to verify part compatibility and specifications.
