Pulse DC power supply B5-71/5-PRO

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.

It is especially effective for use in products made of composite materials (including with honeycomb filler). Distinctive features: The AD-42 IP is a compact acoustic system sensitive to changes in mechanical impedance caused by product defects. The indication of the device indicates that there are voids, non-adhesives, delaminations or changes in the structure of composite materials (including with honeycomb filler and laminated plastics) under the sensor. The device is used to monitor various materials and their combinations. The energy consumption of the unit is low because the converter is switched on when the sensor is placed on the monitored product. Being light enough, the device allows you to perform monitoring in hard-to-reach places or in confined spaces. The results of the control can be stored in the built-in non-volatile memory and transferred to a PC. Converters Options: - 3 types of converters for various tasks Emitters: - 1 or 2 on each converter Switching-on: - The converters are switched on when they are placed on a controlled object.
