Design and calculation of dual-use spiral mobile devices for horizontal and vertical, according to the principle of screw drive meet the needs of the weak magnetic detection technology. The device consists of the support part, guide part and transmission part, simple structure, may be supporting the use with weak magnetic equipment for the handheld single point measurement, and drive probe mobile to complete the measurement and maintained liftoff value unchanged in mobile. Carry on a large number of weak magnetic detection experiments using the device, the results proved that this probe mobile device easy to use, reliable mobile precision to meet the testing requirements.
Can the ASTM heat distortion test provide more than just a single-point measurement?
