SENSOR SOLUTIONS /// Model 834M1 Rev E 9/2015 Page 1 MODEL 834M1 ACCELEROMETER SPECIFICATIONS  Triaxial Piezoelectric Accelerometer  <22µA Current Consumption  Wide Bandwidth to 6kHz  Circuit Board Mountable The Model 834M1 is a low cost, board mountable triaxial accelerometer designed for high amplitude embedded shock applications. The accelerometer features a maximum current consumption of 22 micro-amps and incorporates full power and signal conditioning. The model 834M1 is available in ±2000g to ±6000g ranges and provides a flat frequency response up to greater than 6kHz. The standard model 834 offers the same envelope with a lower maximum current consumption of 4 micro-amps.

FEATURES

 ±2000g to ±6000g Dynamic Range  Low Cost Triaxial  Hermetically Sealed  Piezo-ceramic Crystals  -40° to +125°C Operating Range  Single Axis Configurations Available

APPLICATIONS

 Asset Monitoring  Impact Testing  System Wake-Up Switch  Embedded Applications  Instrumentation DIMENSIONS
