Automotive Crash Accelerometer For High-G Impact Events

PCB Piezotronics provides automotive crash accelerometers  for high-G impact events. PCB® Series 3651 sensors are a rugged and reliable drop-in replacement for other models on the market. PCB® offers high-quality crash sensors with a low cost-to-own and exceptional customer support. Model 3651 Piezoresistive MEMS crash accelerometers are offered in both damped and undamped versions for High-G impact events. These models are designed for crash testing, anthropomorphic testing, sled testing and similar applications that take advantage of its low 1-gram mass, standard low transverse sensitivity and standard low zero G offset.

For these types of test applications, PCB® MEMS accelerometers have the following common characteristics: Over range stops set at approximately ±2,200 G, gas damping attenuates unwanted high-frequency vibrations, and a rugged aluminum housing ensures reliability and durability in the demanding applications and environments.

Meeting SAE J211 and SAE J2570 specifications, this model offers a 2000 G full-scale measurement range with mechanical overload limit stops, with a frequency range of 0 to 5000 Hz. They achieve true DC response for measuring long duration shock, which makes them the preferred choice for applications in which integration of acceleration to velocity to displacement may be performed. Both damped and undamped accelerometers are available with transverse sensitivity (≤1%) as an option.

With the same mounting pattern, seismic center and sensitivity as competitive models, these sensors serve as a drop-in functional replacement with the benefits of quality, ruggedness, flexibility and our unmatched commitment to customer satisfaction.

As with all PCB® instrumentation, these sensors come with toll-free applications assistance, 24-hour customer service, and are backed by a no-risk policy that guarantees total customer satisfaction or your money refunded.
