BOUCHE LABS MODEL 5000M (Manual) COMPARISON-ACCELEROMETER CALIBRATION SYSTEM

Bouche Labs Model 5000M Comparison-Accelerometer Calibration System manually calibrates piezoelectric, piezoelectric I.E., piezoresistive accelerometers, and velocity pickups using either Bouche Labs Model 1000Aor 1000AD Primary Vibration Standard Shakers or other primary standard accelerometers. The calibrations performed are traceable to the National Institute of Standards and Technology. The armatures in these shakers are made of beryllium to provide superior high-frequency performance.

The standard accelerometer built into the armature has a resonance frequency exceeding 80,000 Hz. This accelerometer performance together with the beryllium armature provides accurate accelerometer sensitivity calibrations to 25,000 Hz and resonance frequency calibrations up to nearly 60,000 Hz. Velocity pickups are typically calibrated to 1,000 Hz.

The air-bearing feature of the shakers allows for accurate accelerometer calibrations at low frequencies, down to about 2 Hz with the Model 1000AD.

The 5000M is a manual calibration system but may be upgraded to automation at any time with the addition of the items shown on the reverse side of this data sheet. For manual operation, the Hewlett Packard instruments in the block diagram (border in bold) may be eliminated by using equivalent instrumentation already found in many laboratories. Manual switching is employed to alternately connect the test and standard accelerometers to any voltmeter or the DVM.
