P131-2,5-0/18; P131-2,5-0/20; P131-2,5-0/27

Operating frequency: 2,5 MHz; input beam angle: 0°/18°(20°); dimensions 60х60х50 mm

Combined piezoelectric transducers are used for ultrasonic inspection of wheel axles of freight and passenger cars. The testing is performed from a threaded groove (end face) of the axle. Switching between input angles 0°/18°(20°) - using a toggle switch.

Test zones (variants of the method):

  • "axlesoundability" (TR1);
  • middle and far wheel seatof axle, except for the area under the hub outer edge (AR1.1);
  • journal and pre-seat part of axle (AR1.2, AR1.4);
  • seat of axle in the area under the hub outer edge (AR1.3).
