VX-1100 is for a piezoelectric type accelerometer which is widely used for measuring vibration. This compact calibrator is effective for checking operation(sensitivity) sensors before measurement to acquire accurate data.
  1. Built-in sensor amplifier and display in one unit allows direct reading of the sensitivity. This calibrator excites the sensor at a frequency of 159 Hz and acceleration of 10 m/s2 rms, and the sensor outputs can be used as calibration signals for a vibration measuring system.

Feature

  • Standalone unit having three functions of an exciter, sensor amplifier and display
  • Can be used for accelerometers of both charge output type and built-in amplifier type.
    Required amplifier can be selected by switching.(0.5 mA, 2 mA, or charge amplifier)
  • Digital display allows direct reading of sensitivity.
  • Compact and light weight
  • Long time continuous operation(approx. 8 hours)
  • Accessories necessary for measurement are equipped as standard.
  • Carrying case is provided for easy carrying.

Note

● BNC/marco conversion adapter (NP-0021) is required depending on a sensor. Please contact your nearest distributor or Ono Sokki sales office for details.

● Sensitivity display of following sensors are not supported.NP-2106, 2506, 3211, 3331N20, 3560B, 3572, 3574, 3576N10, 3578N10, and 7310.

● The VX-1100 cannot display correct sensitivity of tri-axial accelerometers. Please use other corresponding sensor amplifiers and calculate the sensitivity by that output value.
