Eaton Corp. (Stand A919) has developed a new oil indicator sensor that works with a rotary-wing aircraft’s existing chip detection system to accurately determine oil fluid levels in intermediate, tail rotor and main gearboxes. The system works with existing aircraft wiring and features a cockpit caution panel indicator that detects the presence of oil. The system requires no additional wiring or panel space requirements and minimizes upgrade/retrofit costs.
A miniature transducer is an exact replacement for the present oil sight glass, chip detector, switching circuit module and existing wiring connections. In operation, the sensor is activated at power-up to provide immediate oil level status. It then switches to the chip detector circuit to provide continuous fluid/debris monitoring in flight.
