Industrial metal detectors are very sensitive pieces of equipment. They are very susceptible to external interference’s within the factory environment. The Goring Kerr TEK 21 metal detector is the last analog model manufactured by Goring Kerr and offers limited correction for these type of industrial noise.
Top tips for setting up an industrial metal detector
When installing a metal detection system care should be taken to ensure it’s located in an optimal location. This means free of any excessive dirt or dust (unless using a sealed machine) and free of any external electrical interference or noise. This can come in many forms some obvious and some not so obvious. Here is a top list of things to watch out for.
Electrical installation tips
- Avoid large electrical panels
- Avoid equipment that radiates energy such as microwave heaters
- Shield from walkie talkie emitters or transmitters
When testing the TEK 21 metal detector refer to the user manual for correct electrical connections and precautions. This will help to reduce the false positive rejects that often result from incorrect installation.
One of the most common installation problems found with used metal detectors is the conveying system. Often installed on an existing belt conveyor these detectors can false reject on metal fragments found inside the belt. The most frequently found spot is the conveyor belt seam or splice. The process of splicing the belt together often requires a hot melting iron used to fuse the two belt section together. The iron itself is often the contributor to adding metal in to the belt. The number one tip for installing a Goring Kerr Metal detector on a belt conveyor is to first use a cold splice belt and ensure there are no metal fragments within the seam.
The next area to look at when installing a metal detector on a conveyor system is metal near the opening of the search head. Metal that is within the metal free zone can either cause false rejects simply by moving with normal vibration or through the phenomenon called loop effect. Either one can be resolved by following the installation manual instructions. This is the second most common issue and second tip for using a conveyor metal detector.
