SV-OAT-340 Location and Installation
The SV-OAT-340 is designed specifically to work with the SV-ADAHRS-200/201.
For full redundancy, a second ADAHRS module requires its own OAT probe.
Probe Location
The SV-OAT-340 is an outside air temperature probe. In order for it work properly, it must be
able to measure air temperature accurately. Avoid exposing the probe to sources of heat that
would interfere with outside air temperature readings such as:

Direct sunlight

Engine heat and exhaust

Aircraft interior (back side of probe)

Heated air from the cabin exiting from an open window or cabin air exhaust port
The installation area should have space for a nut and wires on the back side of the probe. It is
acceptable to extend or reduce the wire length if necessary. Reduce the wire length by cutting
out the desired length from the middle of the wires and splicing together the remaining ends.
If there is a backup ADAHRS in the SkyView system, it is acceptable to install a backup OAT
probe a few inches away from the primary probe. Consider running primary and backup OAT
probe wiring together. Tape probe wire pairs together to avoid confusion later.
Installation
The following tools and materials are required for SV-OAT-340 installation:

SV-OAT-340

SV-ADAHRS-200/201

Drill with 3/8” drill bit

9/16” wrench
Do not insert the pins on the ends of the OAT probe wires into the included
connector housing until you are done running probe wiring through the aircraft.
The SV-OAT-340 connector is small and easily lost. One technique to avoid losing
this connector is to temporarily tape it to the top of the SV-ADAHRS-200/201 until
it’s time to insert the wires into the connector.
The following procedures apply to the both the primary and backup probes.
On the outside of the fuselage:
1. Drill a 3/8” hole at the installation location.
2. Feed the wires of the probe through the hole.
3. Feed the body of the probe through the hole.
