The new Endevco model 7264H from Meggitt Sensing Systems (Irvine, CA) is an optimally gas-damped accelerometer for automotive safety testing with target applications that include pedestrian safety, military-vehicle and sled testing. Small in size and mass, the 7264H eliminates irrelevant frequency content generated by breaking glass and metal-to-metal impact. Unlike fluid-damped sensors, it performs consistently over temperatures ranging from -18°C to +66°C (0°F to +150°F). According to the company, using an innovative MEMS design, the 7264H has a much wider frequency measurement range compared to conventional fluid-damped sensors. Key features include frequency response flat from dc to 3500 Hz, full scale range of 1000 g, and .50 to .85 damping ratio. For more information, visit http://www.meggittsensingsystems.com/ .
