The GJT-B series is a new generation of the metal detector.The circuit design adopts digital phase shifting technology, which has stable performance, high detection sensitivity and strong anti-interference ability. Mainly used in thermal power, cement, building materials, coking, mineral processing, paper making, forestry, environmental protection, food processing, vegetable freezing and other industries' belt conveyor processing.It uses the inductance signal when the metal into the sensor coil ,through the electronic technology to deal with and drive the actuator (electromagnet, conveyor tape motor switch, alarm bell) , thus eliminating the harmful metal.

1.The detector has high sensitivity and high quantification.
2.It is designed to have high sensitivity, which is adjustable, and sound & light alarm.
3.Timing function: Its relay can be released with a delay, which is from 1 - 10 seconds.
