  • DC response – long duration transients
  • Mechanical over-travel stops
  • Selectable damping range
  • Small size, rugged
  • Crash and shock testing

 

Model 7264H is a very low mass accelerometer weighing only 1.4 grams. This accelerometer is
designed for crash testing and similar applications that require minimal mass loading, broad
frequency response, and minimum zero shift following the event. It is equivalent in form and fit to the
Endevco model 7264C-2K in that the location of the center of seismic mass is the same.

Model 7264H utilizes a unique and advanced micro-machined piezoresistive sensor, which includes
integral mechanical stops and damping. This monolithic sensor incorporates the latest MEMS
technology for ruggedness, stability and reliability over previous designs. The accelerometer has a two
active arm, full bridge circuit with fixed completion resistors to facilitate shunt calibration. Full-scale
output is 400 mV nominal with 10 Vdc excitation. With a frequency response extending down to dc
(steady state acceleration), this accelerometer is ideal for measuring long duration transient shocks.

7264H has a full scale range of 1000 g and a selectable damping range. It is available with less than
1% transverse sensitivity and less than ± 25 mV Zero Measurand Output as the “TZ” option.
US patent 6,988,412 applies.

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.
