Polysilicon growth video monitor for the detection of silicon rod is in the diameter of the growth process in developed instruments to machine vision method for measuring the diameter polysilicon rods. Advantage of small size, easy to install; video monitoring, reduce labor intensity; generated in diameter - the time the growth curve, with the temperature test data for the automatic control system was provided.

Real-time measurement of the diameter growth of polycrystalline silicon, measurement accuracy: 0.8mm;Established in diameter - time curve, with data storage, analysis and output functions;Real-time transmission of silicon rod diameter to the master control room;With the installation of automatic guidance function.
