Oil Pressure Gauge: Description and Operation

OIL PRESSURE INDICATOR





DESCRIPTION

The oil pressure indicator provides a bar-graph indication of the engine oil pressure. The gauge is calibrated in metric values and is operated, via B53-4, RS22-7 and RS7-1, by a sensor having an electrical resistance value which decreases with increasing pressure. The display has a red surround which is illuminated when the pressure becomes critically low.
