0.01～100 Hz JJG 298-2005 Zero Control Function Low Frequency Vibration Calibration System
HG-5031L- Low frequency vibration calibration system
The low frequency vibration calibration system uses unique photoelectric coding technology to control and generate low frequency vibration signals, which can complete the comparison method calibration of low frequency sensors with high precision and high efficiency. The laser interferometer can also be used for absolute calibration of low frequency sensors. The low frequency vibration calibration system can also generate dynamic deflection signals, and the laser interference deflection measurement interface can be extended to realize dynamic deflection calibration.
