| 摘要 | An oil sensor comprising a holder to which an elongated crystal is fastened that is transparent to infrared light and with a refractive index greater than the refractive index of the oil to be examined, whereby a light source is provided in the holder at a first end of the elongated crystal for transmitting light in the infrared spectrum in the elongated crystal, and detector at a second end of the elongated crystal for measuring the intensity of the light, which during the passage through the elongated crystal undergoes total reflection at a boundary plane at least four times in succession in a contact zone where the elongated crystal comes into contact with the oil, wherein the oil sensor is further provided with at least one temperature sensor to determine the temperature of at least one of the components of the oil sensor. | ||||||
