Sandia Aerospace SAC 7-35 - Manual (Page 14)

2.2 MOUNTING CONSIDERATIONS
The SAC 7-35 can be mounted in any orientation, either inside or outside the pressure vessel.
Mounting location should be chosen to minimize the static pressure line length from the SAC
7-35 to the altimeter. Be sure to allow an ample service loop on the cable to allow for calibra-
tion of the SAC 7-35. You’ll notice that the SAC 7-35 mounting tray has the same hole pattern
as the SAE 5-35 encoder. This will simplify installations where the SAE 5-35 is being up-
graded with the SAC 7-35.
CAUTION: DO NOT mount the SAC 7-35 in
the direct airstream or near either the hot or
cold air ducts.
The STP 78 Outside Air Temperature (OAT) probe is supplied with the SAC 7-35. It should be
mounted in a location away for the engine exhaust or other area that prevent it from accurately
measuring outside air temperature. The OAT probe should never be mounted on a dark painted
surface. This will cause errors in the OAT measurement.
CAUTION: DO NOT mount the Outside Air
Temperature (OAT) probe near the aircraft ex-
haust or prop wash, dark surfaces, transmit-
ting antennas or cabin heaters.
2.3 COOLING
The SAC 7-35 does not require external cooling.
