A FULL RANGE OF ACCELERATION, SHOCK, AND VIBRATION SENSORS FOR TEST, MEASUREMENT, CONTROL, AND R&D APPLICATIONS

  • ICPR and Charge-Output Piezoelectric Accelerometers
  • Capacitive Accelerometers with DC Response
  • Triaxial and Single Axis Configurations
  • High-Amplitude Shock Accelerometers
  • Low-Amplitude Seismic Accelerometers
  • Structural Test Styles with Simplified Mounting
  • Accelerometers for Extreme Environments

PCB's piezoelectric accelerometers feature precision quartz and ceramic shear-mode sensing elements to reduce the effects of base strain and thermal transients. Most contain built-in microelectronic signal conditioning circuitry (ICPR accelerometers) in order to provide a high-quality, low-noise, low-impedance output signal.

All accelerometers are packaged in lightweight titanium or aluminum housings that are precision laser welded to provide a hermetic seal.

Capacitive accelerometers utilize an opposed plate capacitor as their sensing element. A capacitance shift, caused by the deflection of a spring-mass as it is influenced by acceleration, provides precision measurements at low amplitude levels and low frequencies to DC. This design is inherently rugged, stable, and immune to cross axis influences.
