Krautkramer DM-401-3P Probe for a sonic thickness meter

Krautkramer DM‑401‑3P is a probe designed for sonic thickness meters that emits high‑frequency sound waves to determine material thickness by measuring echo return times. Common failure modes in this class of probes include transducer degradation (loss of sensitivity), cable or connector damage, and coupling fluid contamination or loss, all of which can cause erratic readings or no signal. First‑check diagnostics should verify the probe’s power supply voltage and proper grounding, inspect the cable and connectors for physical wear or corrosion, and confirm that the coupling medium is clean and adequately applied before running a calibration check.[oss-gpt-20b] Post Comment
