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.
