Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Optic-electronic device for controlling shells of revolution with improved metrological characteristics A.N. SHILIN, D.G. SNITSARUK, The article presents an optoelectronic device containing a complex mechanical design of a device for setting a nominal size with a linear scale and a unit for compensating for the temperature deformation of a part. The unit for compensating for the temperature deformation of the part allows the result of the measurement to be brought to normal temperature conditions. A metrological analysis of the developed optoelectronic device was made, from which it follows that the developed instrument meets the requirements of the chemical and oil and gas industry for the accuracy of the shells. Keywords: shells of rotation, projection optoelectronic device, positioning device for optoelectronic devices, measurement of geometric parameters, optical scheme for measuring parts.
