Model 834M1 Accelerometer Triaxial Piezoelectric Accelerometer <22A 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. dimensions FEATURES 2000g to 6000g Dynamic Range Low Cost Triaxial Hermetically Sealed Piezo-ceramic Crystals -40 to +125C Operating Range Single Axis Configurations Available APPLICATIONS Asset Monitoring Impact Testing System Wake-Up Switch Embedded Applications Instrumentation Model 834M1 Rev E 32 Journey Ste. 150 Aliso Viejo, CA 92656 www.meas-spec.com 949-716-5377 09/10/2014 t&m@meas-spec.com Model 834M1 Accelerometer performance specifications All values are typical at +24C, 80Hz and 3.3Vdc excitation unless otherwise stated.
