Reference Accelerometer 3120B

Model 3120B is a double ended IEPE Reference accelerometer that determines the sensitivity and frequency response of characteristics of unknown acceleration, velocity and displacement sensors.

Applications in which it is used include:

  • Back to back accelerometer calibration
  • Low Frequency, Low g level measurements
  • NIST traceable calibrations (when used with appropriate electrodynamic shaker, power supply and control system)

The Dytran 3120B is a reference accelerometer.

Firstly, this model has 10 mV/g sensitivity and mounts to a shaker head via a 10-32 tapped hole.

Secondly, a vibration lab with an electrodynamic shaker and control system can use the model to accomplish in house NIST traceable calibrations. It offers back to back comparisons with a double ended calibration standard accelerometer. This is achieved by mounting the test accelerometer directly to the mounting surface of the calibration standard (model 3120B). Then driving the coupled pair with an electrodynamic at various frequencies and amplitudes. At each test frequency the amplitude is set and the corresponding output read from the test accelerometer. To form a complete measurement system, user needs to supply cables, power supply unit and electrodynamic shake system.

Other features include:

  • Stainless Steel
  • Hermetic
  • Calibration Standard Accelerometer
  • IEPE
