Moving laminated metal product detection equipment - has electrical accessories forming oscillating circuit with frequency measuring device

摘要

The equipment detects, without contact, the presence of a laminated metal product in movement, this needing to be only slightly magnetic. It comprises a detector unit including a set of electrical accessories working together so as to form an oscillating circuit, e.g. of the LC type together with a measuring device for the frequency and/or the variation in frequency of the circuit, and means for processing the result. The detector unit can have a number of turns of conductor wire together forming a winding whose dia. is such that the metal product can pass inside it.
