Endevco® model 7264C is a very low mass piezoresistive accelerometer weighing only 1 gram. This accelerometer is designed for crash testing, rough road testing and similar applications that require minimal mass loading and a broad frequency response. This accelerometer meets SAEJ211 specifications for instrumentation for impact testing and SAEJ2570 specification for anthromorphic testing.
7264C utilizes an advanced micromachined sensor, which includes integral mechanical stops. This monolithic sensor offers improved ruggedness, stability and reliability over previous designs. 7264C has minimum damping, thereby producing no phase shift over the useful frequency range. With a frequency response extending down to dc (steady state acceleration), this accelerometer is ideal for measuring long duration transient shocks.
This accelerometer has a full bridge circuit with fixed resistors for shunt calibration. Full scale output is 400 mV with 10Vdc excitation. It is also available with less than 1% transverse sensitivity (“T” option) and less than ±25 mV zero measurand output (“Z” option).
Recommended electronics for signal conditioning and power supply are the Endevco brand model 126 and 136 and model 436, a general purpose three channel DC conditioner and power supply. U.S. Patents 4,498,229 and 4,605,919 apply.
