Metal detector SQ/SQTA

The SQ is a single probe version of the metal detector that can be easily mounted under the conveyor belt. For better protection, use the SQTA version with tandem probe. It monitors your goods from both above and below the conveyor belt.
  • Monitors bulk materials in the mining and building materials industry
  • 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
  • Sturdy aluminum design: particularly robust and easy to clean
Metal detector SQ/SQTA

Features

  • High sensitivity (M6 nuts) at belt speed of 0.1 - 4 m/s
  • Simple operation
  • Can be used near frequency converters, only 3 ft distance between probe and motors or magnets
  • Monitoring and display of internal parameters
  • Optional: Realization as tandem for higher debris heights
  • Optional: complete blanking of magnetite Fe304

Function

The SQ and SQTA 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.

Both are available for belt widths from 1.5 ft to 4 ft. At a belt speed of 0.1 – 4.0 m/s they can easily detect metal parts of the size of about M6 nuts and larger.

For a higher belt speed (M10 nuts) at a belt speed of max. 4.0 m/s, we recommend the metal detectors SQ and SQTA.

Delivery Scope

  • Detection unit/sensor
  • Control unit in stainless steel housing

Application

  • Machine protection against harmful metal parts such as tools or machine parts in the material
