The present invention concerns an oil mist detector which detects and measures the concentration of oil mist (oil vapor) which continuously flows into the engine room of a ship by a small fan in order to more accurately detect and/or measure the concentration of the oil mist (oil vapor) by applying a method using the strength of dispersed light from an infrared ray source. The oil mist detector comprises: at least one infrared radiation source (light source element) (2): at least one infrared sensor (light detection element) (3, 4), wherein each infrared sensor has a primary infrared sensor (3) and a secondary infrared sensor (4) which are respectively arranged in a horizontal line and vertical line in relation to the infrared radiation source (2) while the infrared rays are radiating or when the infrared rays start radiating; and a terminal box (6) for covering a microprocessor (5) which compares the strength of the infrared rays detected by each infrared sensor. Accordingly, the oil mist detector can measure the concentration of the oil mist detected by the infrared sensor. |
