  • Location: LBT Room 402 (CA 0402)

Measurement Info

  • Measurements acquired September 30, 2009

  • Issue: Difficulty in acheiving solid sensor mount due to oil and uneven mounting surfaces. Will repeat and expand measurements using magnetic accelerometer mounts.

  • Triaxial accelerometer orientation (Y axes) and locations:

Accelerometers

  • Low bandwidth triaxial capacitive accelerometer: PCB 3703G3FD3G, SN3376

  • High bandwidth triaxial shear-type accelerometer: PCB 356B18, SN68994

  • Measured with: HP/Agilent Dynamic Signal Analyzer

Y-axis Measurements Only
