BSN75 Quenching Layer Depth Tester Introduction: The quenching layer depth detector adopts the principle of ultrasonic waves. When ultrasonic waves propagate inside the workpiece, due to the different metallographic structures of the hardened quenching layer and the base material layer, ultrasonic waves will scatter during transmission. By measuring the location of the scattered echo, the thickness of the hardened quenching layer can be determined. This is the principle of the quenching layer depth detector.
