A tramp-metal detector which features a microprocessor control system has been built by Goriong Kerr Canada. Goring Kerr’s model gkd-101 consists of an inspection coil assembly mounted above and below a material conveyor and a controller unit which can be installed at the conveyor or at any remote location. A microprocessor in the controller samples the material on the belt 25 times a second, according to a company release. When tramp metal, even that which is buried deep in the material, passes through the inspection coil, a message is sent to the microprocessor. This sets off an alarm, automatically stopping the belt. An automatic rejection device is then activated.
The controller is housed in a watertight, dustproof housing that can stand up to harsh working environments. A vacuum fluorescent display prompts the operator to make simple keyboard responses during operation, calibration, performance-testing and maintenance of the unit. For simple maintenance, a self-diagnostic, fault-finding system helps personnel locate faults and defective components.
No coil balancing or potentiometer adjustments are needed. At start-up, the microprocessor interrogates a tramp metal sample. Then, using the display and keyboard, the operator selects the size and types of tramp metal to accept or reject.
Other features include a data collection system for management, a false trip immunity and a clip find routine.
