ERGUARD® CM 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® CM 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® CM sensitivity:
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® CM has the highest sensitivity among all types of metal detectors and can easily fit into any production line regardless conveyor speed and type or height and width limits. However, when fitting the metal detector into the existing conveyor non-demountable housing of this model causes the necessity to split conveyor belt with its subsequent splicing (lacing).
Metal detector ERGUARD® CM can be mounted on horizontal or inclined conveyor section.
Depending on purpose and application the detector housing can be made of painted or stainless steel.
