Description

Capacitive fuel level sensor — 6″ (150mm) stainless steel probe, 0.255″ diameter (65mm), M10×1 thread (NPT 1/8 adapter available on request only). Outputs a clean 0–5 V analog signal that your EFIS reads directly. No additional capacitance-to-voltage conversion box, no signal conditioning module, no extra hardware, and no calibration procedure required besides the one your EFIS needs.

Why capacitive? Resistive float senders have a mechanical arm, a wiper, and a finite lifespan — they wear out, they stick, and they lie to you in turbulence. A capacitive sensor has zero moving parts. It measures the dielectric constant of the fluid surrounding the probe, which means it works accurately even in steep climb and descent attitudes, slips, and sloshing fuel. No float bouncing around. No arm to bend. Nothing to wear out. Ever.

And it speaks your language. Most capacitive sensors on the market output a raw capacitance value and expect you to buy a separate signal conditioner to convert it into something useful. This one has the conditioning built in. Additionally, it has a temperature-compensating chip on board so your fuel readings will not vary based on temperature. It then outputs a standard 0–5 V signal. Your EFIS doesn’t know or care that it is a cutting edge capacitive sensor with a miniaturized micro controller. It just sees a voltage.

Compatibility: Plug-and-play with Dynon SkyView, Garmin G3X, and any system that accepts a 0–5 V sender input. No adapter required.

What’s included: Sensor probe with integrated lead wire. M10×1 thread with NPT 1/8 adapter included.
