Helping to reduce system maintenance costs
Decades of in-service experience with both float/reed switches, capacitance probes and our state-of-the-art Time Domain Reflectometry (TDR) system. Meggitt's aerospace fluid sensors provide accurate and reliable fluid readings.
The sensors are installed in the fuel or hydraulic fluid reservoirs or inside the gearbox. We also design and manufacture the signal conditioners that can interface with any avionics requirement.
Applications for fluid level sensors
Our fluid level sensors are trusted by aerospace OEMs around the world including Bell, Beechcraft, Boeing, Cessna, CFMI, GE, Lockheed Martin, Pratt & Whitney, Sikorsky and Rolls Royce. They are used on commercial and military, fixed wing or rotary wing aircraft for:
- Fuel systems measurement
- Engine lube oil measurement
How does a float/reed switch work?
The magnetic float passes a reed-switch ladder.
When the switch is closed, it indicates the fluid level and sends a signal to either the avionics or a dedicated gauge.
- Our float/reed switches are not affected by changes in the fluid property and can tolerate temperatures up to 232 C/450 F making them ideal for engine lube applications.
How does a capacitance probe work?
The sensor consists of two metal tubes inside a housing.
As the fluid level changes, the capacitance between the two metal tubes varies and sends a signal to either the avionics or a dedicated gauge.
At Meggitt, we can provide you with a fluid sensor that is specific to your aerospace application and can be further customised to your particular requirements. To discuss what you need in more detail, contact us.
