Hermetically sealed and critically damped piezoresistive accelerometer
The model 2262A series incorporates Meggitt’s own 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 high-reliability 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 and 3,000 Hz (5%), 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 5000Hz, with excellent performance stability over a temperature range of -18 to +93°C.
