Abstract
In order to measure the oil-film pressure in engine bearings, we developed a new piezo-resistive thin-film sensor made of Cu-Mn-Ni alloy with twin-arc shape and reduced and uniform strain sensitivity. This allowed to correct the error in measured pressure due to strain using a thin-film strain sensor made of Ni-Cr-Al alloy effectively. The error in measured pressure due to temperature influence could be also reduced by optimizing the composition of Cu-Mn-Ni alloy. This paper introduces the measurement method and a measurement result in engine bearings using thin-film sensor.
