With automatic detection and control systems are widely applied to various types of printing machines, printing machine such that the efficiency of the speed faster, and more powerful. The proximity sensor is the key member of the automatic control system, because of its wide range of Mach sensor, different performance. Directly related to the speed and performance stability of the printing machine requires careful selection of the sensor.
Running state detection, single or double sheet detection sensor, a double sheet paper printing machinery faults greater impact on print quality, double-sheet printing process is one of the most fault prone. If the double sheet printing process fault has not been detected in time, it will result in printing machines and machine downtime excessive wear, which reduces productivity and shortens the life of the printing press.
Thus printing machinery used in the above single and double sheet detection sensors recommended: TBB-30D25N1-D3, TBB-30D25P1-D3, TBB-30D25P1-DS12, TBB-30D25P2-DS12, upon detection of a case where two sheets of paper, the sensor indicator will light up, while issuing a switching signal, the double sheet is detected.
