The 660534HS fuel flow transducer mounts to the engine fuel line and produces electrical signals that represent the fuel flow. The transducer body has hydraulic fittings that connect directly to the engines fuel line, and a small turbine wheel mounted inside with two precision ball bearings driven by the flowing fuel which incorporate a small magnet that is picked-up by a hall-effect sensor. Transducers based on hall effect technology can operate over a broader range of flow rates and in high temperature environments. This transducer also includes an integrated RTD temperature sensor.
