KST94C-9N - Piezoelectric Probe Accelerometer
My favorite Units:
m/s² g °C °F gr. oz

Overview
  • For automated measurements, for instance in quality control
  • Movable tip guided by air damped piston / cylinder system
  • Linear frequency range by frictionless movement of the sensing element
  • Design guarantees reproducible measuring results
  • Low distortion and sensitivity for environmental vibration
  • Long life expectancy: Over 10 million test cycles
  • Shear-type accelerometer: Low sensitivity to temperature transients; Low influence of base bending effects
  • IEPE output guarantees low EMI under rough environmental conditions; allows long cables
  • Protection grade IP62, oil resistant
  • Probe tip electrically isolated from body
