WHDWeld Hole Detector

Slitting and continuous coil galvanizing plants cannot afford to miss locating a weld seam while processing coils – Logika’s Weld Hole Detector will locate and signal the position of any weld marking hole. This system can prevent a coiling/uncoiling breakout as well as lower scrap costs by clearly locating where coil welds are to be removed. The integrated output relay can be programmed to maintain an alarm signal for up to 4 seconds allowing the operator to slow the line down for shearing. This system uses IR technology at a modulated frequency that cannot be mistaken for other light sources eliminating false detections.
