Claims (1)
２個の感温抵抗素子をオイルレベルの許容範囲の
下限位置と常時オイルに浸つている位置にそれぞ
れ配する一方で、両感温抵抗素子からの信号を比
較することによりオイルレベルが前記下限位置を
下回るかどうかを検出する手段と、この検出信号
に基づき一定時間当たりの下限位置を下回る時間
を計測する手段と、計測時間が所定の基準値を越
えるかどうかを判定する手段と、これが判定され
た場合に油量不足を警報する手段とを設けたこと
を特徴とするオイルレベルの監視装置。 Two temperature-sensitive resistance elements are placed on the detection rod inserted into the engine's oil pan, one at the lower limit of the allowable oil level range and the other at the position where it is constantly immersed in oil. means for detecting whether the oil level falls below the lower limit position by comparing signals; means for measuring the time period during which the oil level falls below the lower limit position per fixed time based on the detection signal; An oil level monitoring device characterized in that it is provided with means for determining whether or not the oil level has exceeded the level, and means for warning of insufficient oil amount when this is determined.
