Automating the Strain Gauge Data Acquisition of Dipole Magnets During Keying and Skinning
Automated data acquisition and processing of strain gauge data provides distinct advantages when compared to the manual system. Capturing of raw strain gauge data automatically from the dipole magnet while it is being keyed or skinned, allows us an immediate view of the relationship between the press pressures and the internal stresses of the magnet. This data is analyzed then converted to engineering units and displayed on the computer screen in real time. By continuously monitoring the strain gauges and the press pressure, movement within the magnet is detected and correlated with the applied force. This data allows “striction” and shifting of the coils to be detected. Because the data has been collected automatically, typographical errors in the data base are not a concern. The data in this “soft form” is available to be analyzed on other computers. The computer can control the press itself and automate the entire process.
