PRODUCT IDENTIFICATION AND POSITION CONTROL DEVICE Russian patent published in 2010 - IPC G01B21/00 

FIELD: measurement equipment.

SUBSTANCE: invention refers to instrumentation and can be used for identification (recognition) of heated metal and non-metal and non-heated non-metal products, as well as non-contact position control sensor of metal and non-metal products considering their thermal state and material type. According to invention, device includes inductive sensing element, electric oscillation generator, two threshold elements, two infrared photoreceivers, pulse former, two logic elements AND, two inverters, logic element OR-NOT, multivibrator with sensing capacitor element, and detector; at that, inductive and capacitor sensing elements and infrared photoreceivers are installed along the straight line in one plane and comprise the device sensing element, and planes of optic windows of infrared photoreceivers, plane of the open edge of ferrite core of inductive element and one of the planes of capacitor sensing element are parallel installed and form the device sensitive surface.

EFFECT: invention allows avoiding false activations of the device from external infrared radiation sources and when external metal objects penetrate into the operating zone of sensing element.
