Appointment: the continuous measurement system allows for continuous measurement of the heating temperature of the industrial bucket, to improve the stability and reliability of measuring the temperature of liquid metal. Due to the fixed measurement position, the system eliminates errors due to the human factor. This method of measuring temperature was researched and invented on the theory of an absolutely black body. The principle of the temperature measurement system is the immersion of a temperature probe into molten steel to determine the temperature. The temperature probe made of an absolutely black body is designed in a special way to receive an infrared radiation signal corresponding to the temperature of molten steel.

The principle of operation of the electroplating thickness gauge: A converter with an induction coil on a ferrite core generates a high-frequency signal (frequency 1 MHz), which is used to create an alternating magnetic field. As the converter approaches the conductive surface, an alternating magnetic field creates eddy currents, the magnitude of which depends on the characteristics of the metal base and the thickness of the coating. In turn, eddy currents create their own electromagnetic field, which can be received by an induction coil. The resulting signal enters the amplitude detector, after which it is transmitted to the processing unit, where it is digitized and displayed on the device readout. In addition to signal conversion, the processor is used to set the required gain, as well as the initial voltage offset, depending on the characteristics of the materials in the controlled object. Features of the device design and advantages of the measurement method The TL-1MP eddy current thickness gauge consists of an electronic unit with a display, a power supply and a converter. The device is controlled using four buttons located on the front panel of the electronic unit. The converter can be disconnected from the electronic unit during transportation or for convenience of storage. The advantages of the device include: - convenience and ease of operation; - small size and light weight, allowing the TL-1MP to be used in difficult conditions with limited access to the controlled area of the facility; - high measurement accuracy; - factory setting of the measuring instrument to the customer's requirements; - high degree of localization of defects due to the small size of the converter. Scope of application: The service life of metal parts and components of mechanisms used in mechanical engineering is largely determined by their resistance to corrosion and surface wear. However, not all metals are sufficiently resistant to external destructive influences. Therefore, various electroplating coatings made of zinc, nickel, chromium, cadmium, tin, copper, silver and other metals are used to protect them. Even small fluctuations in the thickness of protective coatings can significantly affect the performance characteristics of parts, their service life, and interaction with other components. Therefore, measuring the thickness of the metal coating applied by the electrochemical method is important when conducting quality control of products. The use of the TL-1MP eddy current thickness gauge allows non-destructive quality control of electroplating coatings on the surface of metal parts in mass production conditions with special requirements for product quality. The device detects even small mechanical defects, the effects of abrasion, erosion, corrosion on the surface. Due to its ease of use, efficiency and reliability, eddy current thickness measurement is a standard method of quality control of products with electroplated coatings in such industries as mechanical engineering, aerospace industry.

The principle of operation of the device: The principle of operation of the flaw detector is based on the excitation of eddy currents in the controlled product and the subsequent release of a signal at the output of the converter, the amplitude and phase of which are determined by the secondary field of eddy currents. Design features and advantages of the VD-90NP flaw detector. The device has a small-sized case, which ensures its lightness, ergonomics and allows you to mount it on your belt or on your arm. The measurement is performed using a remote converter connected by a flexible cable.

The large and bright display displays the selected operating modes and measurement results in text and graphic form. The VD-90NP is also characterized by: high sensitivity (it detects cracks starting from 0.1 mm in size); dust–and-moisture-proof housing, which makes it applicable for work in the field; large operating frequency range; maximum working clearance up to 10mm; Bluetooth connection; the ability to control products with high surface roughness, up to Rz320 class; light and sound indication of defect detection; wide operating temperature range from –30°C to +50°C; autonomous low-voltage power supply; long continuous operation time from one set of batteries; compliance with the standard GOST R ISO 15549-2009 (ISO 15549:2008). The use of a microprocessor-based hardware and software platform provide it with the following operational characteristics: automatic adjustment when measuring conditions change, including compensating the influence of the gap; built-in calibration modes; saving the measurement results in the internal memory of the device; a large number of stored programs: sets of parameters and measurement modes, both preset and saved by the user so as to repeatedly monitor the same type of products; The Bluetooth 2.0 wireless communication module allows the device to be used in conjunction with an external laptop or mobile device for remote control, transmission of measurement results for further storage, printing, documentation and analysis. Scope of application: The eddy current method is suitable for non-destructive testing and detection of microcracks in products and parts made of any metals and alloys of complex shape, with high surface roughness, through non-conductive coatings, as well as for checking welded joints.
