3BHB000272R0001 UFC719AE01 design originally planned to use Siemens plc226 + Omron encoder + Omron proximity switches, but in the actual engineering work, due to the use of the encoder for the npn-type, plc’s common terminal needs to be connected to +24v, which brings a great deal of hidden trouble to the entire weak power system, after the use of Omron plc, this problem to achieve a perfect After adopting OMRON plc, this problem has been solved perfectly. Due to the application of rotary encoder, the rotary protection function of rotary arm sampling machine becomes accurate, reliable and easy to maintain, which effectively solves the problems of unreliable action and equipment damage caused by the traditional equipment system using travel switch.

3BHB000272R0001 UFC719AE01 automatic rotary arm sampler is a product developed for coal coking plants to control the quality of incoming coal. The sampling device, through careful design, features simple structure, reliable performance, high sampling accuracy, and strong adaptability to difficult to break down foreign matter in coal. The control system adopts “xd–2000 monitoring system” and “programmable programme controller” for secondary control, which not only meets the real time operation and processing of large amount of data, but also achieves the control requirements. The control units, actuators, and detectors have been fully considered for their reliability and anti-interference.
