KS91 - Piezoelectric Accelerometer
My favorite Units:
m/s² g °C °F gr. oz

Overview
  • Shear-type accelerometer: Low sensitivity to temperature transients; Low influence of base bending effects
  • Insulated base avoiding ground loops
  • Protection grade IP44
  • High resonant frequency
  • Wide dynamic range
  • For light test objects
  • IEPE output guarantees low EMI under rough environmental conditions; allows long cables
