Damped piezoresistive accelerometer for shock environments

Endevco has released the Model 2262B, a rugged, gas damped piezoresistive accelerometer for shock environments. This new transducer employs a unique and advanced multi-mode damped silicon piezoresistive MEMS sensing element for exceptional bandwidth with no significant resonance response up to 40kHz.

The device is offered in 1000g, 2000g and 6000g full-scale ranges. The hermetically sealed stainless-steel package incorporates an integral four-pin connector that mates with the company's Model 3915 detachable low noise, shielded cable assembly, sold separately. The new model replaces the now obsolete Model 2262A fluid damped accelerometer.

“The 2262B is desirable for shock applications where there is a need to suppress high-frequency inputs for accurate motion measurements,” said Jennifer MacDonell, MEMS product line manager at Endevco. ”With a frequency response extending down to DC, the new Model 2262B accelerometer is ideal for measuring long-duration transient shocks in applications such as structural response, shipboard shock (per MIL-DTL-901E), and large vehicle testing.”
