DEVICE TO CONTROL MATERIALS AND SUBSTANCES Russian patent published in 2014 - IPC G01N27/00 

FIELD: testing equipment.

SUBSTANCE: invention relates to the field of non-destructive control of materials and substances, measurement of statistic characteristics of random processes. A device to control materials and substances comprises serially connected a source of physical field, an element with a control object, a converter of physical field, and also the first and second conversion circuit, each of which comprises serially connected an accumulating averaging summator and a count block, at the same time the outlet of the first circuit is connected to the first inlet of a computing device, and the outlet of the second circuit is connected to the second inlet of the computing device, the first outlet of which is connected to inlets of strobing of accumulating averaging summators combined into a bus "Measurement time", the first multiplier, the first analogue-digital converter and the second analogue-digital converter, the second multiplier, the first controlled frequency multiplier, serially connected the second controlled frequency multiplier and the controlled phase changer, the outlet of which is connected to the second inlet of the second multiplier, the outlet of which is connected to the inlet of the second analogue-digital converter, and the first inlet of the multiplier is combined with the first inlet of the first multiplier and is connected to the outlet of the first controlled frequency multiplier, the inlet of which is connected to the outlet of the physical field converter, and the outlet of the source of physical field is connected to the inlet of the second controlled frequency multiplier, the outlet of which is connected to the second inlet of the first multiplier, the outlet of which is connected to the inlet of the first analogue-digital converter, in which the outlet is connected to the inlet of the first circuit of conversion, and the inlet of the second conversion circuit is connected to the outlet of the second analogue-digital converter, besides, control inlets of the first and second controlled frequency multiplier and controlled phase changer are combined into a bus "Plant V_m" and are connected to the second outlet of the computing device.

EFFECT: simplification of a circuit of a device for control of quality of materials and substances.
