Tachometer
A 2¼" tachometer is mounted on the right instrument panel adjacent to
the other engine instruments. The tachometer pointer sweeps a scale
marked from 0 to 3500 RPM in 100 RPM increments. Refer to Section
2 (Limitations) for instrument limit markings. The electrically operated
tachometer receives a speed signal from a tachometer generator
mounted on the aft end of the engine between the magnetos. 28 VDC
for instrument operation is supplied through the 5-amp ENGINE INST
circuit breaker on the Essential Bus.
Exhaust Gas Temp / Cylinder Head Temp Gage
A 2¼" combination Exhaust Gas Temperature (EGT) and Cylinder
Head Temperature (CHT) indicator is mounted in the right instrument
panel. 28 VDC for instrument operation is supplied through the 5-amp
ENGINE INST circuit breaker on the Essential Bus 1.
The EGT pointer sweeps a scale marked from 1250° F to 1650° F in
25° F increments. The EGT scale has no limit markings. The
electrically operated EGT indicator receives a temperature signal from
a thermocouple mounted in the left exhaust pipe.
The CHT pointer sweeps a scale marked from 200° F to 500° F. Refer
to Section 2 (Limitations) for instrument limit markings. The electrically
operated CHT indicator receives a temperature signal from a
temperature sensor mounted in the #2 cylinder head on the left side of
the engine.
Oil Temperature / Oil Pressure Gage
A 2¼" combination Oil Temperature and Oil Pressure indicator is
mounted on the right instrument panel immediately below the EGT/
CHT indicator. The instrument is internally lighted. 28 VDC for
instrument operation is supplied through the 5-amp ENGINE INST
circuit breaker on the Essential Bus.
The Oil Temperature pointer sweeps a scale marked from 75° F to
250° F in 25° F increments. Refer to Section 2 (Limitations) for
instrument limit markings. The Oil Temperature indicator receives a
temperature signal from a temperature sending unit mounted on the
engine near the left magneto.
The Oil Pressure pointer sweeps a scale marked from 0 psi to 100 psi.
Refer to Section 2 (Limitations) for instrument limit markings. The Oil
