OPTICAL-MECHANICAL ANGLE GAUGE OF ROTARY TYPE WITH OPTICAL INDICATOR ON BASE OF MULTI-VALUE MEASURE AND WITH PHOTO-ELECTRON RECORDER

摘要

FIELD: measuring technology. ^ SUBSTANCE: facility can be used in metrology, particularly for measurement of plane angle. The gauge consists of at least carrier of dial scale and a pointer, one of the two is immovable, while turn of an object specifying the measured angle is conveyed to another one. The multi-value gauge of two or more rays forming a flat semicircle or several semicircles serves as the pointer; also rays appear simultaneously or alternately; notably, the gauge maintains reference angles between separate rays. An external optical source radiates rays with reflecting facets of a prism or pyramid located on axis coaxial to a photo-receiver of panoramic type. The photo-receiver is located on internal cylinder surface and functions as a carrier of the dial scale. ^ EFFECT: improved metrological and weight-dimension characteristics as well as workability of facility at simultaneous increased reliability. ^ 4 cl, 2 dwg, 2 tbl
