Detailed description
GJT - F series metal detector using differential transformer type sensor can be assembled, adopted in the circuit design of metal detection technology and latest digital phase-shifting and related testing technique, with 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, 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, so as to detect harmful metals.
Main features:
Sensitivity debugging quantization;
High sensitivity design can detect large metal; Sound and light alarm.
Detection range: iron, aluminum, stainless steel, alloy and other metals.
Control output: a pair of relay contacts normally open and a pair of normally closed.
Timing function: delayed release of the relay after the absorption of the relay, the delay time is 1-10 seconds.
Installation notes:
1. When the amplitude of the belt conveyor frame is less than 0.5mm, it can be mounted directly on the belt frame, and if the amplitude is more than 0.5mm, the mounting bracket should be installed.
2. The input voltage of the machine is ac 220V plus or minus 10V. If the supply voltage exceeds this value, it should be equipped with stable voltage supply .If the above two items exceed the specified value, the metal detector may have the wrong action and affect the normal operation of the equipment.
