500 mV output Piezoresistive Accelerometer Meggitt Sensing Systems introduced Endevco Model 2262A, a rugged, hermetically sealed, critically damped piezoresistive shock accelerometer with 500 mV full scale output, designed to support automotive, aerospace and general in-house laboratory structural, environmental, and impact testing requirements, including transient acceleration measurements on structural members. With available ranges of 1000 g pk and 2000 g pk, the Endevco model 2262A Series incorporates the company’s semiconductor strain gauge elements in a bridge configuration, allowing for low-impedance output with 10 VDC excitation. Sensing elements are housed within a rugged, hermetically sealed stainless steel stud mount package. These accelerometers can withstand shocks of up to 2,500 g and 5,000 g, respectively, with performance that is unaffected by humidity or altitude. With frequency response to 1,500 Hz and 3,000 Hz (5 percent), respectively, the accelerometers are able to provide a broad useful frequency range. Sensor output is enough to directly drive most data acquisition systems without amplification. Viscous damping, with a ratio of 0.7 (typical) extends the useful frequency range of the model 2262A and reduces spurious, high-frequency vibrations. This DC response accelerometer offers a usable frequency range to 5000 Hz, with excellent performance stability over a temperature range of -18°C to +93°C (0?F to +200?F).
