ON798 series products adopt the international advanced technology and micro-chip digital signal processing technology, adopt know-how of high sensitivity and intelligentized location show and counting system. Products have very strong anti-interference capability, to suit more complex environment use.

1. ON798 LCD control panel gives you a good operation environment. Real time level display. An automatic counter function and automatic checking function.The conveyor belt is made from nonpoisonous material. 2. When sensors detect a broken needle or a iron piece,an alarm signal can be given out. It is designed for universal AC power supply (full range). 3. When the broken needle or other magnetic metal is found, the machine gives out an alarm, in the same time, the conveyor belt stops & return automatically.If the alarm is given out normally, the probe will give out a light to indicate a object place where the broken needle or other magnetic metal is. 4. Twelve grades sensitivity adjustment. 5. Optional function: printing reports with a printer.
