油耗传感器自1980年在我厂投入批量生产以来,销量较大。但用户使用一段时间后意见很大,反映精度超差。经过对产品质量分析结果,确认为精度超差的主要原因是密封圈在柴油、汽油介质中工作后膨胀与基体之间形成间隙而漏油,因而影响产品精度。 Fuel consumption sensor since 1980 put into mass production in our factory, sales of larger. However, users have great opinions after using for a period of time, reflecting the ultra-precision. After the product quality analysis results, identified as the main reason for the accuracy of tolerance is the seal in the diesel, gasoline medium after the expansion of the gap between the matrix and the formation of oil leakage, thus affecting product accuracy.
