Welding Position Detection Sensor 【Makome Research Institute】 Metal Non-Destructive Testing
ES-5278
Welds that cannot be visually detected are identified using eddy currents. Detection is possible even under paint and plating (electroplating).
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 the workpiece, we will investigate whether detection is possible free of charge.
