LABORATORIO ELETTROFISICO AMH-DC-TB-S | SOFT MAGNETIC MATERIALS: RINGS, BARS, STRIPS AMH-DC-TB-S Permeameter AMH-DC-TB-S Permeameter is a variation of the model AMH-DC-T-S Permeameter and provides additional features to measure, bar and strip shaped soft magnetic material in addition to toroids and rings. The measurement of bars and strips are made in a closed circuit condition using the model LEP-SB electromagnet (Sanford-Bennett type), made of highly permeability material. The bar samples must be linear with a uniform cross section area. Pole shoes are used to complete the closed circuit configuration for the measurement. The H field is determined by measuring the excitation field closest to the sample with a Hall probe. This measurement is accomplished by detecting the tangential components of H field in the separation surfaces of the magnetic media. The induction B inside the material is determined measuring the flux F from a pick-up coil. Example: B = Φ/(NB• A), where A is the cross section of the specimen and NB is the number of turns of the coil. When measuring bar samples, windings are not necessary. The sample is simply inserted into a pick-up inductive coil with the proper diameter, which contains the Hall probe. The measuring cycle is fully automatic, and is controlled by Laboratorio Elettrofisico exclusive software (Argon 1.0), resulting in complete characterization of the material under test. The Model AMH-DC-TB-S meets the International Standards IEC 60404-4, ASTM A341 and ASTM A341M-16.
