MINIATURE DEVICE FOR RAPID ASSESSMENT OF MOTOR OILS Russian patent published in 2016 - IPC G01N33/28 

FIELD: measuring equipment.

SUBSTANCE: invention relates to analysis and can be used for analysis of motor oils in field conditions. Miniature device for rapid assessment of motor oils consists of a detection unit, power supply unit and a disposable or reusable container for the oil sample, tightly connected with the help of thread with a unit of detection. Detection unit consists of sensitive measuring element (piezo-sensor) based on piezoelectric resonator with film coating, selective to volatile substances-markers of state, miniature excitation circuit, located inside a detection unit under the panel with the Piezoelectric sensor, recorder to a microprocessor for registration of signal of the piezo-sensor with three colour indicators. Actuation of the piezo-sensor signal variation rate is determined indicators in vapors of oil and depends on the degree of its development. Detection unit is connected to power supply unit with possibility of autonomous power supply from power supply unit built into the element or power supply network, on one of side surfaces of the power supply unit are arranged on and power indicator button, and in its lower part there are outputs for charging device and tire for connection with recorder.

EFFECT: invention provides simple mobile control and compact device, which preserves its operational characteristics and allows quickly obtain information on state of the motor oil in field conditions without sample preparation.
