Vibration Transducer Calibrator Model
VM-3B
Brief Description The model
VM-3B, Vibration Transducer Calibrator, is a useful with capability
of generate broad-band signal for system frequency response test.
All accessories of Shaker can be mounted inside the portable housing
of VM-3B that leaves no extra accessories to be carried during the
field operation. VM-3B utilizes advanced digital technology. The
waveform was generated via a digital signal source which is
precisely controlled by the internal clock of the digital circuitry.
The result is a sine-wave with high accuracy in both waveform and
frequency. VM-3b will calibrate sensors with frequency 10Hz, 20Hz,
40Hz, 80Hz, 160Hz, 320Hz, 640Hz and 1280Hz. VM-3B has all the
accessories to meet your need. The accessories include linearity
calibration kit for proximity probe transducer, dynamic calibration
kit for proximity probe transducer.
- Field calibration of vibration monitoring systems
- Field calibration of both seismic and proximity probe
sensors
- Digital accuracy in frequency, waveform and display
- Reading in acceleration, velocity and displacement until
with English/Metric, Peak/RMS
