Method of welding seam positioning in RT

The research of the Hall elements and the distribution of magnetic fields indicates that the RT system composed of Hall Elements,display lamp,MCU,screen,functional buttons and external shell,compared with traditional inspection systems,has the characteristics of simpler structure,more stable performance,higher precision and expanded functions.The production and application of smaples verefy the system is qualified to solve the problems in engineering positioning.The instruments consisting the RT system are easy to operate,carry and realize mass-production mass-application,and has stable performance,high sensitivity and low cost.
