Tectron T-2000 Metal Detector What size metal can the detector trip on?

Every time a new customer calls in they ask the same question.  Their interest is whether or not the metal detector will trip on a piece of metal that can damage their equipment.  They know what size metal will cause damage, and they want to know if the metal detector can see smaller pieces of metal.

So, what is the "Minimum Detectable Size" (MDS)?  First, you must decide which model is best suited for your application.  The Model T2000 is fine if you are protecting an impact crusher or a shredder/hog.
The Model 8600 is the best choice for protecting cone crushers that are gapped down to 3/4 inch.  If the application requires very small metal to be detected, then the model 5500 is the best choice.  The next step is to determine the aperture, which is done by adding four inches to the maximum burden height with lumps.

Once the aperture has been determined, the charts below can be referenced.  Select the aperture from the chart that matches the calculated number.  Check the metal size along the aperture line.  Select the metal detector that has the metal size that is closest to the target metal size.  There are two charts, one for carbon steel and the other for carbon steel.
