Resonant Pitch/Catch Probe
The Resonant Pitch/Catch Probe (RPC-02) is a revolutionary probe that is capable of detecting flaws in nearly any material including solid graphite, honeycomb, solid laminates and metal-to-metal bonded structures. The trick to our success in finding flaws in a wide range of materials is our patented Tuned Resonant Inserts or TRIs at significantly faster scanning speeds with increased sensitivity and little or no scrub noise. Our probes are capable of detecting and discerning far side and opposite wall defects. The hand probe is designed to scan assemblies with fasteners installed. Every material has a physical property known as a resonant frequency. Our TRI’s are designed to resonate within themselves to closely match the physical properties of most materials. The RPC-02 can be used in standard pitch/catch or pulse/echo mode. Pulse/echo mode replaces the current resonant probes on the market without the use of couplant. The unique design of our TRI’s increases the sensitivity of our probes from a measureable 5 to 10 times more than any probe of its type available on the market. Even with the remarkable increased sensitivity, the unique design has reduced the scrubbing noise to nearly undetectable levels. The reason for very low scrubbing noise is that the probe drive voltage requires only 100 millivolts to 20 volts peak to peak. The industry standard instruments have outputs from 200 Volts to 700 Volts peak to peak to drive their probes. The tip spacing of our probes is another important factor for eliminating noise which ensures complete acoustical wave coverage and maximizes the probability of flaw detection. Each TRI is assembled with precision, spring loaded pressure for consistent accuracy in production and in the field when testing.
