Model 10B10-X Piezoelectric Accelerometer

  • Normalized charge sensitivity (typ. 10.2 pC/g)
  • Temp. range -300º F to +500º F (-184 to +260º C)
  • Low base and case strain sensitivity
  • Flat charge sensitivity vs frequency
  • Flat charge sensitivity vs temperature
  • Mounted resonant frequency 30 kHz

The 10B10-X (side connector) and 10B10T-X (top connector) accelerometers are general purpose piezoelectric vibration transducers designed with wide operating temperature range for use in the charge mode. The factory adjusted sensitivity of 10.2 pC/g (typ.) is maintained for all units.

Calibration of each accelerometer is accomplished by comparison to a NIST traceable reference. Using a UD Model APEX SL-C Digital Calibration Control System, a continuous calibration curve is plotted from 10-10,000 Hz., showing percent deviation of charge sensitivity as compared to the sensitivity measured at the 160 Hz. reference frequency.
