◆Applies to belt scale, quantitative feeder, electronic measure belt scale, belt speed checking device.
◆Use DCS to actualize telecontrol operation.
◆Two kinds of screen to choose, LCD or VFD, wall-mounted type or embedded type to adopt different environment.
◆Corrects zero point, belt deadweight, belt speed and totalization automatically.
◆Adopts all-digital and parameter input setting mode, practicality and analog calibration mode.
◆Functions of malfunction hint, malfunction signal purview choice and stop when alarm.
◆Functions of signal collection, error correction, state judgement, running display, PID regulation, DCS 
communication and so on.
◆Adopts flash mode to access data, can save all process parameters automatically when losing power 
supply, when turn on the equipment again, the equipment will keep running in the original process parameters 
that before losing power supply.
◆Adopts high credible elements, combine with advanced anti-jamming technology, stand against highly in static, spark, electromagnetic interference.
