Research on Measuring Method of the Thickness of Quartz Bulb Shell Based on Hall Effect

Abstract:

The hall sensor based on Hall Effect is in direct proportional to hall voltage produced under different magnetic field intensity, and the measuring probe designed according to principle of Hall Effect is used to measure the thickness of metal halide lamp arc tube quartz bulb shell. It is required to place magnetic steel ball in the bulb, the distance between the magnetic steel ball and probe is the thickness of bulb shell, which is in direct proportional to hall voltage produced by hall sensor in the magnetic field of magnetic steel ball. It is required to make use of single-chip machine, A/D converter, amplifier and others to constitute as a hardware circuit to conduct collection, data processing and value conversion for hall voltage and use LCD to show the thickness value of bulb shell.
