This system is capable of vibration testing up to 10 pounds and detecting defects that produce noise, such as loose screws, particles, etc. Right from the start of PIND testing, B&W patented the first MIL-STD compliant system outperforming the competition by over 30% better detection rate as tested by the NBS (now National Institute of Science and Technology) in a well known 1978 study (NBSIR 78-1590 NASA).
Until now there has been no significant improvement to the PIND test systems. Now the particle (or noise) is recorded in digital format and can be easily recalled for post test analysis. This advancement finally provides the ability to distinguish a particle from other noise that the PIND system has detected. The optional Transient Detector is another failsafe, detecting interference from stray RF and other sources.
