摘要: There is provided a gas concentration-detecting device for detecting the concentration of in oil, which capable oil with accuracy, irrespective temperature and even when degraded. The includes two electrodes being arranged such that are opposed to each other spaced from by predetermined distance, capacitance amplifier outputting signal indicative dependent on between electrodes. distance set value equal or larger than at an amount drift output variation starts gradually decrease as increased.
