SBThe Type Electromagnetic Magnet is a new generation of double yoke and double adjustable structure electromagnetic magnet from Koehler Technology GmbH in Germany.SBType electromagnet, its magnetic field air gap is adjustable in both directions, the double yoke structure forms a closed magnetic circuit, has good rigidity, and the magnetic field direction is horizontal; Yoke inclined type45The angled seat is convenient for taking and placing samples, as well as for combining with other equipment.
SBThe design of the electromagnetic coil with a reasonable magnetic circuit and pole size100mm—250mm, weight from200KG—1920KGTo form a series of products. The electromagnetic coil is finely processed to ensure the coaxial alignment of the pole and the maximum number of ampere turns of the wire package. It can be condensed to the smallest volume, and can obtain the strongest magnetic field per unit volume of the wire package for every kilowatt of excitation power. It can also ensure a large smoothness around the working air gap. The electromagnet can be naturally cooled or internally cooled with water cooling to ensure that it can be used at normal temperature.SBThe electromagnetic coil has a wide range of air gap adjustment, easy replacement of pole heads, and is suitable for various magnetic measurements.

4Various supporting software and high-precision adjustment brackets and other accessories
|
|
4.1 Supporting software (upper computer software)
The software can set the DC power supply current value and generate a controlled electromagnetic uniform zone magnetic field by controlling the DC power supply current output; The software can set the target magnetic field value, achieve the target value after the system works, and automatically input it into the test table. The measured data needs to be manually input. After the tester completes the test from low field to high field, the software automatically generates a measurement table and measurement results. The testing standards are formulated according to the standards of the Chinese Academy of Metrology. Test data and tables can be stored in the database for archiving. Support printing test results.
4.2 Adjustment bracket (displacement platform)
The displacement platform is made of non-magnetic materials. Users can manually do itX,Y,ZMovement in direction,Move the probe steadily to a certain position and fix it. The positioning accuracy is0.1Millimeters. Through the displacement platform, the probe can be accurately positioned in the uniform magnetic field area, eliminating the influence of position and angle.
