GJT Mwtal Detactor
GJTmetal detector is designed by our company basing interantinal advanced technology. GJT metal detector is used to assemble the differential transformer type sensor, the circuit is adopted in the design of new metal detection technology - digital phase-shifting and related testing technique,it has a series advantages,such as stable and reliable performance, high detection sensitivity, strong material suppression characteristics, good anti-interference ability. This product is mainly used for thermal power, cement, building materials, paper making, mining, food, chemical and other industries.Inorder to test the raw materials mixed in various kinds of metal material, it is the use of metal into the sensor emf induction signal generated by signal amplification circuit to drive the executing agency action,finally harmful metals are detected.
1.Highly sensitive and quantitative debugging.
2.High sensitivity to detect extra large metals and acoustic-optical alarm.
3.Timing:time release after relay absorption,with a delay time of 1-10 seconds.
4.Detection range: iron, aluminum, stainless steel, alloy and other metals.
5.Control output: a pair of relay contacts normally open and a pair of normally closed.
It is widely used together with belt conveyors in thermal power,cement,paper,non-magnetic mining,forestry,environment protection,building materials and other industries Detect.magnetic impurities to protect the rest of the equipment in good condition.
1. When the amplitude of the belt conveyor frame is less than 0.5mm, it can be installed directly on the belt frame, and if the amplitude is over 0.5mm, the mounting bracket should be installed.
2. The input voltage of the machine is ac 220V plus or minus 10V. If the power voltage is over this value should be equipped with a stable voltage supply. If the above two items have been set, the metal detector may have misoperation and affect the normal operation of the equipment.
