Dilution monitoring system for filter cigarettes.

摘要

A dilution monitoring system for filter cigarettes comprises pairs of pressure sensors (114,120) provided individually for left- and right-hand manufactured filter cigarettes, a dilution processor card (62) adapted to receive pressure signals from the pressure sensors (114,120) through an A/D converter (61), and a server computer (39) connected to the processor card (62) by means of a communication line (38) and including a CRT. The dilution processor card (62) computes the respective dilutions of the individual filter cigarettes in accordance with the pressure signals, and stores the computation results into a RAM (68). Thereafter, the processor card (62) obtains quality informations, such as the average, frequency distribution, and standard deviation of the stored dilutions, for each group of the left- and right-hand filter cigarettes, also stores the quality informations into the RAM (68). The server computer (39) receives the quality informations transmitted from the processor card (62), and displays them in the form of a graph or table on the CRT.
