Calibration Notes
-
If the sender is used at full, uncut length: proceed directly to fuel level calibration in the EFIS—no Empty/Full calibration required.
-
If the sender is cut shorter: you must perform a calibration in two stages before EFIS calibration:
-
Set EMPTY calibration by applying power with the signal line shorted to ground, wait ~10 seconds (for post‑March 2013 models), then measure a stable 0.3 V output.
-
Set FULL calibration by fully immersing the sender in a tank, repeat with jumper, wait ~20 seconds, confirm ~4.0 V output.
-
-
Once sender-level calibration is complete, proceed with the standard fuel‑level calibration in your EFIS system.
Installation & Compatibility
-
Wiring:
-
Red wire = +11–28 Vdc supply
-
Yellow wire = signal output (0.3 V to 4.0 V)
-
Black wire = ground
-
-
Compatible with many MGL EFIS and RADAC systems such as the Extreme EMS (signal interpreted in either ohms or voltage mode depending on RADAC switch setting)
-
No mechanical floats—ideal for rugged aviation installations and less prone to mechanical failure.
Mechanical & Environmental
-
Probe body: concentric tubing (metal inner/outer with polyester or polymer insulators)
-
Housing dimensions: approximately 0.72″ tall and 2.625″ diameter
-
Materials: corrosion resistant, epoxy‑sealed electronics for durability across a wide temperature range (approx. −40 °C to +85 °C)
