Metal detector QLC/QLCTA
The QLC is a single probe version of the metal detector that can be easily mounted under the conveyor belt. For better protection, use the QLCTA version with tandem probe: it monitors your goods from above and below the conveyor belt.- Monitors bulk materials in the building materials industry or mining
- Self-adjusting and easy to install
- High-quality components ensure reliability and long service life
- Detects ferrous and non-ferrous metals; iron oxide and ore are ignored
- Probe and amplifier are immune to vibration and resistant to weather, dirt and stone chips
- Particularly robust and easy to clean
Features
- Good sensitivity (M10 nuts) at belt speed of 0.3 - 6 m/s
- Smple operation
- Can be used close to frequency converters, only 6.5 ft minimum distance between probe and motors or magnets
- Belt widths from 1.5 ft to 6.5 ft
- Monitoring and display of internal para-meters
- Optional: Realization as tandem for higher debris heights
- Optional: complete suppression of magnetite Fe3O4
Function
The QLC and QLCTA metal detectors offer good metal sensitivity for monitoring bulk materials in the mining and construction industry.
They are extremely durable, insensitive to vibrations and resistant to weather, dirt or stone chips. They are easy to install, handle and maintain.
At a belt speed of 0.3 - 6.0 m/s, they can easily detect metal parts about the size of M10 nuts and larger.
For higher sensitivity (M6 nuts) at a belt speed of max. 4.0 m/s, we recommend the metal detectors SQ and SQTA.
