- Abstract:
- Many high quality Hall-type magnetic field sensors of advanced technology are customary available. We have experienced the use of Hall type sensors in non-destructive testing of material volume reduction due to corrosion and abrasion of iron tubes of different diameters as used for the heat exchangers, and gas pipelines.
Some results achieved by using a prototype assembly are presented. This consisted of a mechanical sensor moving support and a PC based measurement set for data recording and processing. Data gained are interpreted from the diagnosis point of view as the loss of ferromagnetic material and/or the thickness reduction. A program enabling to calculate distorted magnetic field has been developed with the aim to improve the design of sensor and to provide the measuring system with a sort of built-in intelligence for the evaluation of tests results. - Keywords:
