Shadin Avionics DC Fuel Flow to Frequency Converter

This part number designates a remote-mounted, solid-state aircraft interface module manufactured by Shadin Avionics. It functions as a specialized telemetry converter designed to process analog engine parameters, factory-installed or retrofitted across high-performance single-engine and twin-engine general aviation airframes.

Description

This unit has been bench tested by an FAA certified repair station and it comes with an 8130 single release dated 7/21/2026.

Key Technical Capabilities
  • Analog-to-Digital Signal Conversion: Receives incoming continuous fuel flow telemetry in the form of an analog DC voltage signal from legacy engine sensors or fuel flow indicators, translating the raw voltage into a digital frequency output.
  • Proportional Frequency Output: Generates a highly accurate digital output signal with a frequency that scales directly proportional to the raw engine fuel flow volume, bridging the gap between legacy airframe plumbing and modern digital electronics.
  • Fuel Management Interoperability: Packages the processed frequency output into standard formats required by electronic fuel management systems and moving-map navigators, allowing fuel burn and endurance mapping to display directly on cockpit screens.
  • Unmodified Offset Transmission: Passes through raw data streams cleanly without calculating an internal offset baseline, relying on the receiving glass cockpit display or flight management system (FMS) to correct for any natural fuel system signal offsets.
  • Rugged Flight Deck Profile: Enclosed inside a lightweight, sealed casing engineered to pass rigorous operational low-temperature testing down to -30°C alongside high-altitude decompression testing profiles.
