Accelerometer solves the ringing problem in shock measurements

PCB Piezotronics has introduced a new mechanically isolated, electrically filtered near-field or far-field pyroshock sensor that is capable of measuring up to 100,000g. Designed to solve the ringing problem in shock measurements, the model 350B01 is an ideal sensor to measure High-G shock and harsh pyroshock events such as found but not limited to metal-to-metal impact, explosive bolts, impact tools, and stage separation testing. This 100kg sensor completes PCB's Series 350 shock accelerometer product line, which includes ranges of 5000g, 10000g, and 50000g. Mechanical isolation aids in removing frequency content outside of the useful bandwidth of 20kHz, and minimizes zero-shift associated with non-isolated accelerometers. Electrical filtering reduces signal ringing and clipping. The unit is hermetically sealed and case isolated for use in electrically noisy environments. Each pyroshock sensor is provided with a full scale Hopkinson bar calibration service at no extra charge, in accordance with MIL-STD-810G, Method 517, Change 1. All piezoelectric ICP shock accelerometer sensing elements are fabricated from a proprietary mixture of piezo-ceramic materials in-house at PCB's ISO-9001 certified facility in the USA, where vertically-integrated manufacturing allows complete control of product quality, says the company.
