PHOTOELECTRIC INCREMENTING BITMAP TRANSFORMER Russian patent published in 2006 - IPC G01B5/02 G01B11/02 

FIELD: engineering of measuring equipment, namely, engineering of incrementing means for measuring linear displacements.

SUBSTANCE: photoelectric incrementing bitmap transformer has body, measuring rod, guiding rod, bitmap mating device, consisting of measuring and indicating bitmaps with emitters and photo-detectors, platform, held on measuring rod, closing spring, one end of which is held on one side of platform. Transformer is provided with additional spring of lesser rigidity in comparison to rigidity of closing spring, and moving rollers, mated, respectively, to closing and additional springs, plane of position of which is perpendicular to axes of rollers rotation. In guiding rod measuring force adjusting device is positioned in form of block with possible movement relatively to guiding rod and holding in place by means of screw for example, mounted in the groove of guiding rod, and a longitudinal, through aperture is made, wherein closing and additional springs are positioned, first ends of which are held on different sides of aforementioned block, and another end of additional spring is connected to platform on the side opposite to holding of end of closing spring. Roller of additional spring is mounted on axis of bracket, positioned at the end of guiding rod, with possible movement along the axis of the latter.

EFFECT: engineering of reliably operating bitmap transformer making it possible to decrease oscillations of measuring force, adjust measuring force, improve precision of measurements.
