Abstract
The lubrication of an engine crank shaft is monitored using a wheatstone resistance measuring bridge one of the arms of which includes lubricating oil ducts between the crank shaft and crank case of the engine, balanced against a reference resistance provided by a resistance measuring cell through which the engine lubricating oil flows. The resistance measuring cell may have an external heater for heating the oil in the cell to a temperature compatible with that of the oil in the engine bearings when the engine is running.
