46. OIL PRESSURE GAUGE.
The electric oil pressure gauge uses a transducer which varies resistance
with pressure,
a.s reference.
17. FUEL PRESSURE GAUGE.
The fuel pressure gauge is of the electric type, using a transducer as
reference, and is calibrated in pounds per square inch and indicates the pres-
sure to
the fuel injector.
18 & 19. FUEL QblANTlTV INDICATORS.
The fuel quantity indicators are used in conjunction with two float-operated
variable- resistance transmitters in each fuel tank. The tank-full position of
the
Iransrnitter float produces a maximurn resistance through the transmitters,
perrnittiing minimum current flow through fuel quantity indicator and maxi-
mum pointer deflection.
The instruments are calibrated in gallons(Liters Op-
tional) of fuel.
