Bently Nevada Machinery Condition Monitoring

173M1055 Rev. ADescription
The Portable Vibration Calibrator provides a field tested
method for on-the-spot dynamic verification ofaccelerometers, and velocity pickups.
The Portable Vibration Calibrator incorporates a built-in sine
wave oscillator, power amplifier, electrodynamic shaker, NIST
traceable reference accelerometer, digital display, charge
amplifier, and internal memory. The Portable Vibration
Calibrator is completely self-contained and operates onbattery or AC power.
The built-in reference accelerometer is attachedpermanently to the shaker armature, maximizing theaccuracy between the reference accelerometer and the test
transducer. The Portable Vibration Calibrator is designed toprovide long-term reliable performance over the frequency
range of 5 Hz to 10 kHz. The Portable Vibration Calibrator canbe used for a variety of applications that include:
lll

Verification of vibration transducers and related
vibration test systems.
Verification of connector and cabling integrity.
Confirming machine vibration alarm trip points are set
properly and ensure end-to-end functionality ofvibration monitoring systems.
