Instruments

Sonex plans to continually test new digital aircraft instruments as they become available. These instruments tend to change rapidly as advances in technology are made. The pricing has been trending down with increased competition and additional available features.

There are two companies that Sonex feels have the best valued instruments in the market, MGL Avionics (Stratomaster) and Grand Rapids Technologies (EIS).

Sonex takes your order for these instrument packages and has the units drop shipped from the manufactuers in the United States. Sonex-specific fuel level probes are available for both systems from Sonex Aircraft, LLC. Sonex provides competitive pricing and installation support for either of these instrument options. We will make sure you receive the correct set-ups for your Firewall-Forward Options on your Sonex, Waiex, or Xenos.

Sonex Fuel Level Probe

Sonex Fuel Level Probes are available for either the MGL Stratomaster or the Grand Rapids EIS. Note: If you purchase one of the instrument packages above from Sonex Aircraft, LLC a fuel level probe is already included in the package price.

The Sonex Fuel Level Probe screws into existing provisions in the Sonex fuel tank (1/8" NPT). You must specify which instrument the probe will be used on (different probes provided for Grand Rapids EIS [Capacitive-type sender] and MGL Stratomaster [Resistance-type sender]). Note: Resistance-type fuel level senders are also preferred for Dynon instruments.

AeroConversions K-Type and J-Type CHT Probes

Tired of ruining your old CHT probes every time you touch your spark plugs? Introducing AeroConversions CHT Probes for Jabiru, AeroVee, and other VW-based Engines!

Unlike traditional CHT probes which are installed under spark plugs, our new AeroConversions CHT probes are made to be attached to cylinder heads independently. For AeroVee, or any other VW head engines, the AeroConversions CHT Probe is screwed into the cylinder head with a small self-tapping screw. For Jabiru Engines, the probes are installed under cylinder head bolts.

AeroConversions CHT Probes are sold in sets of 2 probes for $30, for use on any CHT instrument compatible with K-Type or J-Type senders. Note: Stratomaster Instruments require K-Type probes; Grand Rapids EIS requires J-Type probes.
