The phd system is frequently employed in recognizing the micro holes in the aluminum foil, Which might have presence in / generated in the aluminum foil while cold cup formation. The tablet / capsule may get exposed to the climate / atmosphere due to, After packing micro hole and hence may loose its characteristic / properties. The received signal form the aluminum foil is termed as detection signal. This detection signal is given to the plc of the blister forming/tablet, Capsule filling machine, Which interninsure to segregate the strip form the line.
