Description
Magnetic Flaw Detector (Magnetic Yoke) NOVOTEST MPD-DC applies in circumstances where the electric equipment mustn’t be used or prohibited by the rules.
Device is used during magnetic particle inspection (where it is applicable) according to ASTM E 709, ASTM E 1444, ASME Section V Article 7 and MIL-STD-1949.
Magnetic Flaw Detector NOVOTEST MPD-DC is used to detect surface and subsurface cracks of all kinds (flake, lack of fusion welded joints, tears etc.) in structures made of ferromagnetic materials.
The device has two permanent magnets placed in a cylindrical shells, which are connected by a flexible magnetic wire, so it can be used for MPI of remote locations, corner welds and other products of various shapes and sizes.
Feature
Magnetic Flaw Detector NOVOTEST MPD-DC can be used in cases if user can not use electromagnets, when supply of power is difficult or restricted by rules of safety (during works at height; working in the field conditions; testing of internal surface of tanks, boilers; etc.) at operating temperature from 30 °C below zero to 50 °C above zero and relative humidity up to 95% at 35 °C .
