  • Digital tachometer with air gap adjusting yoke insertable through holes in the tachometer housing
    Patent number: 4890059
    Abstract: A magnet equipped rotating generator wheel cooperates with a stationary sensor cassette containing wire pulse sensors. The sensor cassette is electrically and mechanically fixed to a stiff circuit board to form a structural unit. The generator wheel and structural unit are enclosed within a housing having inner and outer parts, the outer part having a planar front surface. The structural unit is adjustably mounted to the planar front surface of the outer part of the housing of the tachometer. A pair of holes are formed in the circuit board at the air gap location and a corresponding pair of holes in the planar front surface so that the air gap between generator wheel and sensor cassette can be adjusted by inserting a spacing yoke.
