This equipment consists of “sensors” mounted on the crankcase side of a diesel engine and a “alarm device” that collectively controlled by RS485 communication means. The equipment uses a natural diffusion system that does not require mechanically moving parts, such as a suction mechanism, driving air or piping. An infrared diffuse reflection principle is used. The mist detection section consists of a light emitting element (LED) and a light receiving element (PD: photodiode). The light emitted from the LED of the sensor unit is diffused and reflected by the oil mist in the sensor hood, and then received by the photoreceiver diode (PD). After amplification and A-D conversion, the output from the photoreceiver is input to the CPU for arithmetic operation, and then transferred to the controller as the oil mist density data. Each sensor is separately installed on diesel engine cylinder with independent oil mist detection function and no connection between each other. Compact design, improved reliability and easy maintenance are realized by the use of the light scattering system for detection of mist density. The maximum number of detection points is 32. The system is very flexible for layout and installations of oil mist detection and alarm device.
