The Multi Finger Caliper adopts mechanical detection fingers to detect the inside diameter (radius) , judging the distortion, transposition , holes , cracks, inside wall corrosion and other casing damages through the diameter (radius).
Features
-
Every arm has a independent sensor, and a high resolution in peripheral direction.
-
Between detection arm and sensor, it’s a flexible connection, easily to make sure the flexibility and repeatability.
-
Special type has the function for H S de ng, can be used in high H S well.
