China GJT-F Industrial Metal Detector for Belt Conveyor - Reliable Suppliers and Factory for Bulk Material Safety
Technical Characteristics
1. Sensitivity debugging quantization; senior name design section detect oversized metal and sound and light alarm.
2. Detection range: iron, aluminum, stainless steel, alloy and other metals.
3. Timing function: delayed release after relay absorption, time 1-10 seconds.
4. Control output: relay contact a pair of normally open, a pair of normally closed.
5. Installation: Sensor installation, belt frame amplitude should be less than 0.5mm, more than 0.5mm, the sensor bracket should be installed separately.
6. Note: The power supply should be equipped with stabilized power supply when the power supply voltage is unstable.
7. Its sensors shell is made of stainless steel or plastics steel, good anti corrosion ability, suitable for terrible environment and easy to install.
8. Control cabinet adopts dual-door structure with stainless steel shell, waterproof and dustproof.
9. Position and belt speed can be adjusted and the types of mineral can be selected, digit set, good stability and wide application.
10. Sensitivity can be adjusted intelligently. (The metal detector upon detecting the presence of metal, the conveyor belt becomes automatically stops.)
11. Multi-level anti-inference measures are taken to avoid wrong actions effectively.
12. General purpose and easy to upgrade.
13. Both magnetic and non-magnetic materials can be detected.

Frequently Asked Questions (FAQ)
What types of metals can this detector identify?
The metal detector has a wide detection range and can easily identify iron, aluminum, stainless steel, alloy, and other metals. It is capable of detecting both magnetic and non-magnetic materials.
What happens when metal is detected on the conveyor belt?
Upon detecting the presence of oversized metal, the system triggers a sound and light alarm, and the conveyor belt automatically stops to allow for removal.
Is the metal detector suitable for harsh environments?
Yes, the sensor shell is made of durable stainless steel or plastics steel, providing excellent anti-corrosion abilities. The control cabinet also features a dual-door stainless steel structure that is both waterproof and dustproof.
Can the sensitivity of the metal detector be adjusted?
Absolutely. The sensitivity can be adjusted intelligently and features sensitivity debugging quantization to ensure accurate detection based on your specific requirements.
What industries commonly use this equipment?
This equipment is highly versatile and is widely used across various heavy industries, including cement, steel plants, metallurgy, mining, paper manufacturing, and the coal industry.
What is the standard voltage required for operation?
The standard voltage required for the metal detector is 220V±10% at 50Hz. Note that if your power supply voltage is unstable, it should be equipped with a stabilized power supply.
