Single plate metal detectors ERGUARD SCM

ERGUARD SCM

ERGUARD SCM is series of industrial metal detectors designed for detection of various metal inclusions in bulk or piece goods transported by conveyor belt.

Metal detectors ERGUARD SCM are most commonly applied to control product quality and also to protect process equipment from damage caused by metal objects sticking in machinery.

Principle description:

The principle of operation of metal detectors ERGUARD SCM is based on inductive balance method. The metal detector unit has three circuits: one transmitter and two receivers with null potential difference in case of metal absence. When tramp metal gets inside the detection field, the established balance is disrupted causing the detector to transmit a signal to the control panel by activating audio and visual alarm, rejection device or stopping conveyor for the time necessary to remove a product containing undesirable metallic inclusions.

The main characteristic of the metal detector is its sensitivity expressed in minimum diameter values of steel, brass and stainless steel balls, which the metal detector is able to detect at minimum belt speed and the most disadvantaged location of the balls in the detection area.

ERGUARD SCM sensitivity:

  • ferrous metal (Fe) Ø ≥ 3.0 mm
  • Non-Ferrous Metals (non-Fe) Ø ≥ 5.0 mm
  • Stainless steel (SS440) Ø ≥ 5.0 mm

The detector sensitivity values mentioned above were obtained under ideal conditions and may vary depending on installation site, aperture size, frequency at which the detector operates as well as electromagnetic properties of the product. ERGUARD SCM has the lowest sensitivity and most often used for bulk control. Its design feature allows mounting this detector easily into any production line. The detector housing consists of one plate which allows mounting it easily under conveyor belt. Single plate metal detectors are typically used when the height of the product layer on the belt does not exceed 100 mm. However, if it is needed to detect massive metal inclusions in big layer of product (up to 500 mm), i.e. low sensitivity is required, then single plate metal detectors are best suited for solution of such tasks.

When choosing the model of ERGUARD SCM metal detectors the following should be considered:

  • product coarseness (sizes);
  • electrophysical properties of product;
  • shape, size, material and orientation in space of all possible tramp metals, which a product may contain;
  • type of feeding and product movement speed through the detection area of the metal detector;
  • detector operating conditions;
  • way of rejection of the product with tramp metals from the "pure" product.

Technical specifications of ERGUARD SCM:

  • Industrial protection class: IP54;
  • Number of operating frequencies: maximum two. Values of operating frequencies can be selected depending on the product characteristics, it enables sensitivity increase;
  • Memory for 10 products allows you to adjust the detector quickly and accurately;
  • High vibration resistance due to its special design;
  • Automatic system of self-diagnostics (adjustment) of the metal detector necessary to ensure its stable performance;
  • Three levels of access to settings of detector parameters in order to avoid unwanted access of the personnel;
  • Digital Signal Processing;
  • Human-engineered and simple user interface.

ERGUARD SCM metal detector can be supplied as such extended option as ERGUARD ESCM. Depending on the tasks set and customers order metal detector can be completed with reject assembly and conveyor. Optional configurations are listed below.
