Welding Position Detection Sensor 【Makome Laboratory】 Metal Non-Destructive Testing
We detect welding positions that cannot be identified by visual inspection or image sensors using eddy currents, and detection is possible even under paint or plating (gold plating).
This product is an eddy current welding position detection sensor that utilizes changes in eddy currents at the target welding position. This product consists of a detection sensor (hereinafter referred to as the sensor) and a controller. The sensor converts the eddy current detection signal into a digital signal and communicates with the controller via serial data. The controller performs signal processing and threshold comparison. The comparison result is output as a switch signal. *If you lend us a workpiece, we will investigate whether detection is possible free of charge. Please feel free to contact us.
