  • Abstract Lubrication is the lifeblood of mechanical device during the operating conditions, so that the lubricating oil detection becomes one of an important modern technology. The operator can be as early as possible to know whether the abnormal wear occurs by detecting concentration of ferrous debris in the lubricating oil. Detecting the viscosity of lubricating oil can also allow the operator to monitor the deterioration degree of lubricating oil due to environmental factors, in order to ensure whether the lubricating oil losing its effectiveness. Our laboratory previously developed a prototype of integrated apparatus for detecting the concentration of ferrous debris and the viscosity of lubricant in a single process. This study focuses on improving this prototype, so that the apparatus possesses a LCD displayer and commercialization. The design of the integrated apparatus contains a sampling unit, a measurement unit of the ferrous debris concentration, a measurement unit of the viscosity, a data acquisition system, and LCD displayer panel.
    In measurement unit of the ferrous debris concentration, Hall IC is used as a sensor to measure the concentration of ferrous debris by detecting the change of magnetic flux density between the magnetic poles due to the stacking of ferrous debris. In the measurement unit of the viscosity of the lubricating oils, the piston is used to squeeze the oil into the tank to measure the viscosity by detecting the load.
    These two units are integrated into a measuring device, and there is no interference between the values measured by the Hall IC and the load cell. Finally, these two signals are fed to a personal computer for data analysis to obtain the concentration of ferrous debris and the viscosity of lubricant. Consequently, the operator can directly observe the measured results.
