KB12VD - Piezoelectric Accelerometer
My favorite Units:
m/s² g °C °F gr. oz

Overview
  • Premounted insulating flange M10
  • Air damping for resonance attenuation and overload protection by friction coupling
  • Extremely sensitive piezo system provides excellent resolution and lowest noise
  • For seismic and building vibration measurement particularly at low frequencies
  • IEPE output guarantees low EMI under rough environmental conditions; allows long cables
