electrical circuit—the digital phase change and related checking technique with stable performance, high checking sensitivity and antijamming capability, it is mainly used in the lines such as thermal power generation, cement, papermaking, mineral, environment-protection and building material etc. As the metal passes through the electric magnetic field of senor, the changing signal that is treated and driven by electronic technique is generated.

Adopting the special CMOS chip digital electrocircuit technique,it is suitable to the lines that use the belt to convey the bulk magnetic and nonmagnetic material. The grade of ore and belt-speed can be adjusted. Featuring with digital set, self-checking function, convenient adjustment and maintenance and intellectualized sensitive adjustment, it can detect and eliminate the metal efficiently to enhance the quality of product and protect the crushing equipment.
