摘要:The invention provides an improved method of monitoring a toothed gearwheel comprising the steps of: positioning a Hall element (202) adjacent to the gearwheel (106) to detect variations in magnetic flux (110) as the gear wheel (106) rotates;comparing the output of the Hall element (202) to a set of threshold parameters andthus outputting a binary signal (112) indicative of the presence or absence of a tooth(108), wherein different threshold parameters are provided for different teeth (108). Theinvention further provides an apparatus (102) suitable for carrying out the above methodcomprising a Hall element (202), placed between a magnet (104) and a gear wheel (106)to detect variations in magnetic flux (110) as the gear wheel (106) rotates; a processingmeans (204), for comparing the output of the Hall element (202) to a set of thresholdparameters and thus outputting a binary signal (112) indicative of the presence orabsence of a tooth (108); and a data storage means (206) for storing a set of thresholdparameters for each individual tooth (108).
