Ultrasonic flaw detector А1220 ANKER is designed for ultrasonic inspection of anchor bolts from 20 to 40 mm in diameter of understructure of steel supports of the overhead control system. The instrument can be as well used to evaluate the condition of anchor bolts of understructure of the metal floodlight towers.
Law frequency flaw detector А1220 ANKER works in the echo method mode at which the A-Scan of the signal is represented in real time. Condition of the anchor bolts is evaluated by presence, level and location of the amplitude of the ultrasonic signal on the sweep (X scale) reflected from the counter surface of the bolt and registered at its longitudinal scanning.
