AIRPLANE & SYSTEMS DESCRIPTION
Oil
pressure signals
are
generated
from
a
pressure
line/transducer
combination.
An oil
pressure line
is
routed from
the
upper
front of the engine case
to the
rear engine baffle. At
the
Oâfie,
the oil
pressure
line
is
connected
to a
transducer. This
transducer produces
an
electrical signal which translates
into
a
pressure reading
at
the instrument panel gauge.
Oil
temperature signals
are
generated from
a
resistance{ype
probe located in the accessory case.
As oil
temperature changes,
ihe probe
resistance
changes. This resistance is translated into
oil
temperature readings
on
the cockpit indicator.
the OIL PRESS light
extinguishes.
NOTE
The low oil
pressure switch
is also wired into
the
Hobbs
(hour) meter. When pressure exceeds
20
PSl,
a
ground
is
supplied
to the
hour meter,
completing
the hour
meter
circuit.
I
left side of
the
instrument
originating
in the
engine
as temperature portion
of
I
no
range
markings or
red
lines. Marking
