Product Description
The 128-389001-3 is a capacitance-type fuel quantity probe installed directly in aircraft fuel tanks. This sensor converts fuel height into an electrical signal transmitted to the flight deck fuel quantity indicator or computer. The probe connects to a signal conditioner that processes the capacitance measurement and displays remaining fuel quantity to the flight crew.
Installation requires tank access and calibration per the aircraft maintenance manual to ensure accurate fuel readings across the full tank range. Compliance with FAA TSO-C55a standards ensures reliable operation in general and commercial aviation fuel systems.
