B&W LPD-DAQ4000 Particle Impact Noise Detection (PIND) System

The B&W LPD-DAQ4000 Particle Impact Noise Detection (PIND) System is a computer-based controller that detects loose particles from a device under test. The B&W LPD-DAQ4000 is programmed in compliance with MIL-STD 883 Method 2020 and MIL-STD 750 Method 2052. The MIL-STDs, the B&W LPD-DAQ4000 allows users to create unlimited custom tests with variations in parameters to achieve unique requirements. The B&W LPD-DAQ4000 exposes the device under test to physical stimulus of shock and vibration. All interferences are recorded digitally for further analysis. The B&W LPD-DAQ4000 is capable of testing packages up to 10lbs at 20gs and stops the test when the particle noise threshold has exceeded.
