High Sensitivity ICP® Accelerometers

Highlights:

  • Resolution down to 1 µg rms broadband
  • Extended low frequency measurement capability
  • Hermetically sealed

Applications

  • Building and floor vibration monitoring
  • Earthquake detection
  • Structural testing of bridges and foundations
  • Geological formation studies

High sensitivity ICP® accelerometers are specifically designed to enable the detection of ultra-low-level, low-frequency vibrations associated with very large structures, foundations, and earth tremors. These sensors typically possess exceptional measurement resolution as the result of its comparatively larger size, which furnishes a stronger output signal and a lower noise floor.All units are hermetically sealed in a titanium or stainless steel housing. Models that include a 2-pin, military style connector provide the added benefit of being electrically case isolated for superior RF and EMI protection.

Vibration monitoring of civil structures and treasured monuments can be an essential practice for ensuring the safety of occupants or protecting the structure from catastrophic demise. Studies have shown that crowds of people in a stadium grandstand or theater balcony impart tremendous forces and harmonic motion to the structure when the crowd acts in a synchronous manner. Earth tremors, foot traffic, and trucks and trains can impart vibration, which can cause a structure to sway, shift, crumble, or collapse. Permanent-monitoring high-sensitivity accelerometers are used for trending, analyzing, and alerts when structural motion exceeds established safety limits. This provides the information for corrective or evasive action.

Decaying infrastructures, particularly bridges, have received heightened awareness in recent years. Among the several techniques for determining the health and longevity of civil structures, vibration measurements are used for continuous monitoring, modal analysis, and structural integrity investigation. High sensitivity accelerometers generate signals in response to a variety of stimuli including traffic, wind, and programmatic impulse. When analyzed, these signals provide insight for determining the condition and safety of the structure. This investigative analysis can lead to recommendations for remedial construction or further monitoring.
