ICP® Mechanical Impedance Sensor

ICP® Mechanical Impedance Sensor

Model 288D01 Mechanical Impedance Sensor simultaneously measures an applied, driving-point force and response acceleration of a test structure for determining parameters such as mechanical mobility and mechanical impedance. The unit consists of a precision, shear mode accelerometer and a quartz force sensor in a common housing. Installation is primarily facilitated at the structural excitation points, in series with a stinger and vibration shaker.

Highlights


  • 100 mV/g [10.2 mV/(m/s2)] acceleration sensitivity
  • 100 mV/lb [22.4 mV/N] force sensitivity
  • 0.7 to 7000 Hz frequency range
  • 19.2 gram weight

Applications


  • Structural Testing
  • Modal Analysis
