ERGUARD® GM is a series of industrial metal detectors designed for detection of various metal inclusions in free fall products with their further rejection.
Metal detectors ERGUARD® GM are most commonly applied to control product quality and also to protect process equipment from damage caused by metal objects sticking in machinery.
The principle of operation of metal detectors ERGUARD® GM 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 and rejection device which rejects tramp metals from the main flow in automatic mode.
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® GM 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® GM has high sensitivity and can detect and reject all types of metal unlike standard metal separators.
Metal detector ERGUARD® GM can be mounted either on a frame with a hopper or built in gravity pipeline.
Depending on purpose and application the detector housing can be made of painted or stainless steel.
