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
