Description
EDITORIAL NOTE There are two pages of Description There are two pages of Claims Magnetic Field Measuring Assembly PROVISIONAL SPECIFICATION FOR THE INVENTION ENTITIJED: MAGNETIC FIELD MEASURiNG ASSEMBLY Field of invention The present invention relates to a magnetIc field measuring assembly. The application is to measure the magnetic field vector, magnitude and position on a magnetic product. Background to the invention There have been issues with inspecting and maintaining magnetic equipment in general and the mining industry specifically. Current practice utilises a hall probe held on the surface of the equipment. This method has many inherent potential for errors, has limited repeatability of results and does not incorporate any relative reliable position monitoring of the magnetic readings. Data logging is also limited. The initial application for this invention is the accurate measurement of the magnetic fields around a magnetic drum separator. Wet drum magnetic separators are used in many industries including coal processing. When the magnets in the drum are damaged, insulated with magnetic material such as magnetite, deteriorate or move out of position the external magnetic field is altered resulting in a reduced operational efficiency and reduced recovery. The purpose of this invention is to provide a product that can produce accurate, repeatable magnetic flux density readings in specified locations. In the case of a magnetic wet drum these readings will be measured for the magnetic flux density around the outside skin surface of the drum. Summary of Invention In the first aspect the invention provides a magnetic field measuring assembly comprising: * A sensor to measure the magnetic field vector * A sensor to measure the location of magnetic field vector measurement - A Data logging device to combine the measured information. The sensor to measure the magnetic field vector may be incorporated in a moulded casing and may have options to measure a number of field vectors. The sensor to measure the location of magnetic field vector measurement may utilise any combination of mechanical, lazar, gravity or other measurement methods. Although the invention is primarily designed for attachment to facilitate the measuring of magnetic field vectors around a magnetic drum it could be incorporated in any situation where the magnetic field vector measurement is needed.
