Tunnel Type Metal Detectors are a closed circuit system and the detection sensitivity in the inner center of the tunnel depends on the tunnel dimensions. Negative effects such as physical environment, product effect, magnetic interference, vibration are disadvantageous for tunnel type metal detectors in terms of sensitivity. The tape on which the metal detector will be applied must be vibration free, antistatic and not dirty. Metal detection sensitivity in tunnel type metal detectors is inversely proportional to the tunnel interior dimensions. As the tunnel interior size increases, metal detection sensitivity decreases, and as the tunnel gets smaller, metal detection sensitivity increases. It is recommended where more sensitive detection is required.
