摘要：
A sensor for detecting the level of oil in the crankcase of an internal combustion engine. The sensor has a generally tubular body and at one end a thin metal plate to which is bonded the piezo-electric element. The plate, and hence the piezo-electric element, are oriented in the crankcase such that they are generally perpendicular to the level of the oil within the crankcase.
