METHOD TO MONITOR LUBRICANT OIL QUALITY AND DEVICE FOR ITS REALISATION Russian patent published in 2015 - IPC G01N33/30 

FIELD: instrumentation.

SUBSTANCE: invention relates to the field of technical diagnostics of technical systems, having a closed lubrication system, and may be used to monitor quality of motor oils in process of operation. They assess extent of oil contamination in process of operation, at the same time they additionally simultaneously assess antifriction properties, extreme pressure properties, temperature and viscosity of oil, and by received characteristics they make a conclusion on oil suitability for further use. A device to monitor lubricant oil made in the form of a feeler, comprising a purity sensor, a rotation drive, an information processing unit, at the same time additionally in the feeler there are sensors of viscosity, bearing capacity and friction torque, temperature and oil level, besides, all sensors are made in the form of separate modules placed in a flexible tube from material resistant to oil exposure, and also there is an additional panel for placement in an operator's cab, informing about current condition of oil.

EFFECT: expansion of functional capabilities and increased objectivity of received data.
