    摘要: An exhaust gas analyzer capable of real-time analysis of the concentration, temperature, and the like of an exhaust gas component in a cross-section of an exhaust path in a spot-wise manner reduces analysis cost. An exhaust gas analyzer (10) comprises sensor units (11) to (14) disposed along the exhaust path, which comprises an exhaust manifold (3) for the engine (2) discharging exhaust gas, an exhaust tube (4), a first catalyst device (5), a second catalyst device (6), a muffler (7), and an exhaust pipe (8). Each sensor unit includes an optical fiber (25) for irradiating the exhaust gas with laser light, and a detector (26) for receiving the laser light emitted by the optical fiber that has been transmitted through the exhaust gas. Based on the laser light received by the detector, the condition of an exhaust gas component, such as its concentration, temperature, and the like, is measured for the analysis of the exhaust gas. The sensor unit has a through-hole (21) allowing the passage of exhaust gas that is formed in a shape matched with a cross-sectional shape of the exhaust path. The infrared laser light R is emitted via the optical fiber (25) into the through-hole (21), travels across the exhaust path, and is then received by the detector (26).

    摘要: An oil-degradation detecting apparatus that can more accurately judge oil degradation and a mechanical system having a rotating part or a sliding part and including the oil-degradation detecting apparatus are provided. Two plates (21, 22) are disposed in an oil flow path (11) so as to be parallel to each other, an ammeter (24) measures a current that flows when an AC voltage is applied between the two plates (21, 22), a voltmeter measures the voltage between the plates (21, 22), and a signal processor (processor) (31) determines the electrical conductivity and the dielectric constant of the oil (10) based on the measurement results from the ammeter (24) and the voltmeter (25) and judges degradation of the oil (10) based on the electrical conductivity and the dielectric constant.
