3027B

加速度传感器

概述

The

Dytran 3027B

is a double ended IEPE reference (comparison) accelerometer, offering a convenient means of determining the sensitivity and frequency response characteristics of unknown acceleration, velocity and displacement sensors. A vibration laboratory already equipped with an electrodynamic shaker and control system can easily incorporate use of the model 3027B to accomplish in-house NIST traceable calibrations. Model 3027B offers a >10 mV/g sensitivity, and mounts to a shaker head via a 10-32 tapped hole.

Back-to-back comparisons with a double ended calibration standard accelerometer, such as the

 Dytran

 model

3027B

, entails mounting the test accelerometer directly to the top mounting surface of the calibration standard (model 3027B) and driving the coupled pair with an electrodynamic shaker system 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, the user will need to supply the cables, power supply unit and electrodynamic shaker system. The model 3027B should be used for low frequency, low g level measurements.
