Sabreline distribution and chemical composition of the material, and can be used to control sheet, pipe and other rental directly to the mills for cold and hot rolling in the dynamics.

Known x-ray measuring parameters of the car containing the x-ray source, consistently located in the radiation flux of the first and second detectors x-ray test object placed between the first and second detectors, the controller and the Registrar of patents of the Russian Federation 2179706, 2189008, CL G 01 15/02].

A disadvantage of the known x-ray gauges is limited functionality, consisting in control only of the thickness of the rolled stock with a fixed chemical composition and in need of a set of model measures the reference thickness of each rolled material to achieve the specified accuracy of the probes.

The closest technical solution to the claimed represented the x-ray measuring the parameters of the car containing the x-ray source, consistently located in the radiation flux of the first and second detectors x-ray test object placed between the first and second detectors, the controller and the Registrar [RF patent Avraamova technical solutions is in x-ray measurement unit rental, containing the x-ray source, consistently placed in the stream of cure of the first and second detectors x-ray test object located between the first and second detectors, the controller inputs connected to the outputs of the first and second detectors, and the logger associated with the input with the output of the controller, introduced x-ray protection screen and the third x-ray detector, while the first and third detectors are made of dual chamber (dual), proceedings of the transformative elements which have different sizes atomic number, and outputs a third detector connected to other inputs of the controller, and the third detector is placed parallel to the first, but outside of the primary x-ray flux, and isolated from the first detector and the direct flow of the radiation source x-ray protection screen, in addition, the first detector facing the controlled product as a transforming element with a high atomic number, and the third detector is converted to the product as a transforming element with a lower atomic number.

The technical result of the invention is the extension funkcionalnogo rooms.

The drawing shows a structural block diagram of the x-ray meter. It contains the source 1 of x-rays, consistently placed in the flow of direct x-ray radiation (shown through arrows) of the first and second detectors 2, 3, the third detector 6 x-ray radiation, located parallel to the first detector 2, the test object 4 located between the first and second detectors 2 and 3, x-ray protection screen 5, the controller 7 and the Registrar 8.

The first and third detectors 2 and 6 are two-chamber (dual), whose materials transforming elements have different value of the atomic number (number) Z. Detector 6 is placed in parallel to the first detector 2, but outside of the primary x-ray flux (shown through arrows) and is isolated from the direct flow of the radiation source 1 and the first detector 2 screen 5 of the x-ray shielding material such as lead. The outputs of the third detector 6 is connected to the free inputs of the controller 7. The first detector 2 converts as a transforming element (not shown) for the controlled product 4 with high atomic number of the order of Z=80-90 (for example, Bi is bismuth), and the third detector 6 is turned to its cell battery (included) converts the value of Z materials transforming elements of the detectors 2 and 6 provide different spectral sensitivity of the detectors 2 and 6. To increase the value of the signal-to-noise and reduce distortion of the emission spectrum of the first detector 2 is turned to the controlled product 4 transformative element with a high atomic number Z, and the third detector 6, which converts the reflected x-ray radiation flux from the material of the test object 4, converted to the product 4 transformative element with a lower atomic number Z.

The detectors 2, 3, 6 are used to convert x-rays into an electrical signal. The controller 7 performs the functions of amplification of the electrical signals of the detectors 2, 3, 6, convert (addition, subtraction, division) in the format suitable for playback on the recorder 8, and memorization.

The operation of the meter.

In the process control products 4 anode voltage of the source 1 of x-ray radiation constant support to stabilize its metrological characteristics. The primary x-ray flux is directed towards the first detector 2, which then transmits the product 4 and gets to the second detector 3, while the reflected x-ray flux from the material of the test object 4 hits the detector 6. Electrical signals from the detectors 2, 3, 6 obrabatyvati 8. Electric signals from the detectors 2 and 3 are compared in the controller 7 and the change compared signals can judge the thickness of the test object. Simultaneously with this action are compared in the controller 7 electrical signals from the detector 2 and detector 6, receiving the reflected x-ray flux from the material of the test object 4, and the change compared signals of these detectors 2 and 6 is judged on the value of the effective atomic number Zeffthe material of the test object.

The technical result of the invention is to enhance the functionality of the meter, due to the simultaneous measurement of the thickness of the sheet material and its effective atomic number.
