Non-Contact Internal Flaw Detection Instrument
Spring-loaded, inductive probes sense internal threads by the amount of metal removed or displaced in the tapping / rolling operation. Variations in shape and amount of metal in the electromagnetic field are detected and displayed on a digital touch pad screen.
A plus and minus Accept/reject tolerance is automatically set by comparing known good part voltages with known defective part voltages. Missing, shallow and/or damaged threads are detected as they fall outside the accept/reject tolerance.
Three modes of communication are available; Remote I/O, Local I/O and RS232 for machine control are standard.
Probes are designed specifically to work in harsh manufacturing environments. Unlike other thread detection instruments, which require clean and dry parts, the NCTP’s accuracy is not affected by coolant or oil. Threading processes are 100% verified in-line assuring defects are detected as soon as they occur.
• Signal is generated in under 100ms after the probe has been fully advanced.
• Graphical user interface allows for quick set up.
• Window for upper and lower thresholds, allows for different levels of screening.
The inductive probes are spring loaded to avoid damage from broken taps or mislocated holes. The probes spring back when contact is made causing the voltage reading to remain outside the accept tolerance causing a part rejection.

Without the NCTP-200 these internal defects are unfortunately being detected by customers creating an unpleasant experience. Current users of the NCTP 200 are ecstatic over the systems capabilities. In several cases, very small defects are detected by the NCTP 200, then confirmed through destructive testing.[/one]
