Description

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:

ferrous metal (Fe) Ø ≥ 0.5 mm
Non-Ferrous Metals (non-Fe) Ø ≥1.0 mm
Stainless steel (SS440) Ø ≥ 1.0 mm
