Gia tốc kế 3120B Dytran Instruments
Back–to–back comparisons with a double ended calibration standard accelerometer, such as the Dytran model 3120B, entails mounting the test accelerometer directly to the top mounting surface of the calibration standard (model 3120B) and driving the coupled pair with an electrodynamic shake 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 shake system.
