Metrology

The UNM-1000 allows to detect internal, subsurface and surface defects of different types (cracks, flokens, delaminations, defects of welding seams, etc.) in parts, structural elements, units and mechanisms of industrial units, railway, auto, air vehicles, as well as petrochemical, gas and technological equipment during the manufacturing and repair stages or during routine inspections of the products being in operation. The principle of operation of the UNM-1000 AC flaw detector The magnetic powder method of detecting defects in products made of ferromagnetic materials is based on the ability of magnetic powder particles to settle in the defect zone, where inhomogeneities of the magnetic field created by the magnetizing device arise. Unlike devices based on permanent magnets, magnetic particle flaw detectors allow you to set the current and time of magnetization and automatically demagnetize controlled samples. The UNM-1000 AC flaw detectors allow monitoring of products by the applied field method using various magnetization techniques. To do this, the alternating electric current generated by the flaw detector can be passed through a magnetizing cable or directly through a controlled product connected to the flaw detector using electrical contacts. The value of the current used for magnetization and demagnetization of the product is set by the operator of the device. Design features and advantages The UNM-1000 flaw detector is a portable device, which allows you to control the quality of products made of ferromagnetic materials both in production and in laboratory conditions. The basic set of equipment for magnetic particle flaw detection includes a UNM-1000 magnetizing device, a power cable for power supply from a single-phase AC network with a voltage of 220 V, and technical documentation. At the request of the customer, electrical contacts and a magnetizing AC cable can be additionally supplied. The advantages of the UNM-1000 device of the MANUL series include: the possibility of monitoring both in the applied magnetic field with longitudinal magnetization using power cables, and with circular magnetization by passing current through the controlled product; wide range of magnetization current adjustment from 50 to 1000 A; automatic demagnetization of controlled products; high performance; the device is compact and has light weight; the degree of protection from external influences is at least IP40. Scope of application of magnetic particle control means Due to its versatility, simplicity and ease of operation, the UNM-1000 magnetic particle flaw detector can be used in almost all non-destructive testing laboratories of workshops and assembly shops of the automotive and aviation industries, railway transport, for the needs of civil and military shipbuilding. Also, the UNM-1000 magnetic powder control device can be successfully used in the energy sector, in the production of pipelines, metal structures, construction equipment and related industries.
