If the ordinary thickness gauges are incompetent in the rough applications. Please turn to our AJR Scan-II A/B Scan Ultrasonic Thickness Gauge, which will maximize measurement performance for challenging applications and provide you with the cost-effective measurement solutions.
The working principle of the magnetic coil is to charge the capacitor with a high voltage small current, and then the capacitor instantly discharge the coil and generate a large current on the magnetized coil, which generates a magnetic field. In short, the magnetic charging coil is to charge and discharge the capacitor, so that the coil is used as a load to generate a magnetic field. Small parts should not be centered within the coil, but held close to it where field strength is strongest. The longitudinal magnetic field cutting across the crack attracts and holds iron powder to indicate the crack.
