Particle Impact Noise Detection (PIND)

B&W Engineering Corp., the originators of the first fully MIL-STD compliant PIND system, is pleased to introduce a new generation in Particle Impact Noise Detection (PIND) systems, the BW-LPD-D4000. Our new test system is the one you will need to accurately test cavity devices for particle contamination with the ease you want and reliability that you demand.

Programming of the new BW-LPD-D4000 is so simple that any operator can be trained with ease. Our new digital controller provides the flexibility to comply with the evolving MIL-S TDs or your in-house tests at no additional cost. The constantly digitally displayed frequency and acceleration may be set at any time by the user without reprogramming.

After mounting the device with either the ultrasonic couplant or tape dots supplied, simply depress the footswitch or Start button (or set the Auto Restart feature) and let the testing begin. The Auto Restart feature allows the operator to program a delay between tests for device placement. Throughput can exceed 200 parts per hour. Production is enhanced and your product is protected by using the optional PIND station Test Bench with ESD work surface and operator grounding wrist strap.

Any signal derived from loose particles is transmitted by our patented Particle Sensor with built-in pre-amplifier. The pre-amplification allows low impedance signal transmission which does away with interference caused by cable noise etc. The assembly is acoustically isolated to suppress the reception of mechanical noise.
