Model Number: D20M3

High Precision Tiny Contact Diamete Delay Line Probe - 20MHz 0.125" (3mm) Fingertip Transducer

(Delay Line Replaceable)

Mesurement Range: 0.15 mm - 12.00 mm

This is the best replacement for Waygate / Krautkramer DFR Style Alpha Serial fingertip probe with the same parameters (measuring frequency of 20MHz and element diameter of 0.125" or 3mm)

Good for Krautkramer Branson CL3 (DL) and CL5 Thickness Gauges as in the photos and video here.

Along with connection cable (Lemo to MD) (as Waygate C-604, for Alpha-2, Alpha DFR, CA211A)

Probe and Cable ONLY, Krautkramer CL5, Krautkramer CL3 DL Units are not included, they were used to show the working of D20M3 with these testers.

The last three photos are the comparison of the delay line blocks between this D20M3 transducer and 1) Alpha DFR .125 (0.125" in diameter) and 2) Alpha 2 (0.25" in diameter).

The D20M3 (20 MHz 0.125" or 3mm) probe is a high-frequency, small-diameter, delay-line fingertip contact transducer designed for high-resolution, near-surface, and thin-material thickness measurements (like metals and plastics). These transducers are often used in restricted, difficult-to-access areas due to their small, narrow-diameter design.
