FIELD: pneumatic measuring equipment, possible use for measuring diameter of shafts.
SUBSTANCE: device for measuring diameter consists of measuring element in form of pneumatic measuring bracket with localizing base prism, two nozzles mounted oppositely on the bracket, having common axis with diameter of part being controlled, measuring device made in form of two-channel pneumatic-electronic device, each channel of which is connected to one of nozzles. Two-channel pneumatic-electronic device contains two measuring cameras with pneumatic-electronic transformers, electronic block for processing measurement results, indicator with digital and limiting scales.
EFFECT: increased precision of measurements in broad range of measuring.
