Overspeed Shutoff Detector (OSSD)
The Overspeed Shutoff Detector contains a Flanged Housing and Plunger Assembly which is actuated when the engine becomes unstable. This will cause contact with the Plunger Assembly pushing it into the Frangible Link and fracturing it. This shuts off the signal controlling the fuel, shutting down the engine avoiding catastrophic failure.
The OSSD device is designed for one time usage.
Features
- Based on proprietary Frangible Link technology
- Unique ceramic materials ensure performance over severe thermal and vibration environment
- Sensing head hermetically sealed for high reliability
- Proprietary glass and collapsible seal technology
- MTBF 854,700 hours
Benefits
- No moving parts
- Fast response time
- Guaranteed Activation range 0.030” to 0.070” of linear travel
- Can be setup to directly control fuel shut-off valve
- Rigid harnesses manufactured with onsite CNC bending machines for repeatable 3D geometry
