Demountable metal detectors ERGUARD® DCM


ERGUARD® DCM – серия промышленных металлодетекторов, предназначенных для обнаружения различных металлических включений в насыпных материалах или штучных продуктах, транспортируемых ленточным конвейером.

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

Metal detectors ERGUARD® DCM 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® CM 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® DCM sensitivity:

  • ferrous metal (Fe) Ø ≥ 2.0 mm
  • Non-Ferrous Metals (non-Fe) Ø ≥ 4.0 mm
  • Stainless steel (SS440) Ø ≥ 4.0 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® DCM having high sensitivity can be easily mounted on any conveyor type. Since it has demountable housing it is simply fit into any production line regardless conveyor speed and type or any height and width limits.

Depending on purpose and application the detector housing can be made of painted or stainless steel.

When choosing the model of ERGUARD® 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® CM:

  • 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® DCM metal detector can be supplied as such extended options as ERGUARD® ECM / EDCM. Depending on the tasks set and customer’s order metal detector can be completed with reject assembly and conveyor. Optional configurations are listed below.


ERGUARD® CM / DCM / SCM / ECM / EDCM supplementary options:

  • Detector operating on belt with rivets;
  • Visual and audio alarm;
  • Rejection unit with alarm relay and unloading activation relay for automatic rejection of the product;
  • Rejection unit with a photosensor for automatic rejection of packaged piece of the product;
  • Differentiation of the detected metal: ferrous/nonferrous;
  • Remote control and monitoring of the detector with ModBus protocol with RS485 interface;
  • Installing another interface: RS232, Ethernet;
  • Event counter (real time clock);
  • Conveyor belt speed setting module on the part where the detector is mounted;
  • Beacon (remote warning light);
  • Remote operator’s panel;
  • Remote control with moisture and dust protection degree IP65;
  • Manufacturing of stainless steel housing of the detector for non-food industry;
  • Coating for highly corrosive environment;
  • Increased moisture protection;
  • Additional setting memory for variety of products (over 10);
  • Marking device;
  • Weight rejection device (checkweigher).
