GJT series metal detector

The GJT series metal detector adopts a differential transformer type sensor that can be assembled, and adopts the latest metal detection technology - digital phase shifting and related detection technology in the circuit design. It has stable and reliable performance, high detection sensitivity, strong material suppression characteristics, and excellent anti-interference ability. This product is mainly used in industries such as thermal power generation, cement, building materials, papermaking, mining, food, chemical industry, etc., to detect various metal substances mixed in raw materials. It uses the induction signal generated by the metal entering the electromagnetic field of the sensor, which is amplified and processed by the signal processing circuit to drive the action of the actuator, thereby achieving the detection of harmful metals.
Applicable scope
This equipment is mainly used for detecting magnetic impurities in belt conveyors in industries such as thermal power generation, cement, papermaking, non-magnetic mines, forestry, environmental protection, building materials, etc., to protect the good operation of other equipment.
Technical characteristics
1. Highly quantitative sensitivity
2. High sensitivity design, adjustable sensitivity, and sound and light alarm.
3. Timing function: Delay release after the relay is engaged, with a delay time of 1-10 seconds.

Quantification of sensitivity debugging;
High sensitivity design can detect oversized metals; Audible and visual alarm.
Detection scope: Metals such as iron, aluminum, stainless steel, alloys, etc.
Control output: One pair of normally open and one pair of normally closed relay contacts.
Timing function: Delay release after the relay is engaged, with a delay time of 1-10 seconds.
Installation matters
1. When the amplitude of the belt conveyor frame is less than 0.5mm, it can be directly installed on the belt frame. If the amplitude exceeds 0.5mm, a fixed bracket should be installed separately.
2. The input voltage of this machine is AC 220V ± 10V. If the power supply voltage exceeds this value, a regulated power supply should be equipped. If the above two items exceed the specified values, the metal detector may malfunction and affect the normal operation of the equipment.
