PCB Automotive Sensors, a division of PCB Piezotronics, Inc., Farmington Hills, MI, introduces a new series of DC MEMS shock accelerometers for automotive crash testing. Available in damped and undamped versions, the PCB® Series 3641 and 3651 are designed for applications that require small mass and a broad frequency response, such as crash testing, drop testing and sled testing. Both sensors offer a 2000 G full-scale measurement range with mechanical overload limit stops, and a frequency range of 0 to 5000 Hz. In addition, these models meet SAE J211 and SAE J2570 specifications.
PCB® Series 3641 and 3651 are designed with standard low transverse sensitivity and standard low zero G offset. The Series 3641 and 3651 achieve true DC response for measuring long duration shock. For this reason, they are preferred for applications in which integration from acceleration to velocity to displacement may be performed.
