Throat Metal Detectors

The THS/G21ET series is designed to inspect powders, granules and other loose materials transported in free-fall through tubes and pipelines. When fitted with a deflector, the THS/G21ET becomes a system that detects and removes any contaminating metals, both magnetic and non-magnetic. Alternatively, when mounted on a packaging machine, the THS/G21ET system is able to send a command to produce a double bag around the contaminated product. This can later be identified and removed from the production cycle automatically. Digital analysis of the signal provided by the antenna allows extremely high levels of sensitivity, immunity to interference and operational stability to be achieved. The very high detection speed of the THS/G21ET allows the contaminated portion of product to be removed without slowing down the production flow. The system is designed to communicate with external control systems, either connected directly or via a communications network.
