  ABSTRACT: This study presents a methodology for analysis of the industrial machine alignment in the production line. The level of land subsidence in the area of the industrial machine location was assessed by adopting Hall Effect Sensor (HES). A computer was used for real-time data collecting and displaying the angle of subsidence over operational period. The measurement module consists of two flat-curve permanent magnets mounted parallelly and the magnetic poles which were placed in position that can be generating the magnetic tension force. The center between two permanent magnets was the sensor namely HES placed perpendicularly to the magnetic fluxes. The permanent magnets were the moving parts which can be displaced depending on the inclined angle of land subsidence. Analysis of the relationship between the incline angle of the measurement module and the output voltage from the HES was considered from the function of subsidence angle and magnetic density on X-axis and perpendicular angle (Y-axis) with the resolution of 100 mV per degree. There were two ranges of measurement according to the angle resolution, –20 to 20 degree at 1 degree of resolution per step and –6 to 6 degree at 0.01 degree of resolution per step.
