Description
The AR-200/AR-400 series is a range of high-performance dynamic signal acquisition modules that are designed specifically for vibration monitoring and analysis. The maximum simultaneous sampling rate for each channel on the AR-200 and AR-400 is up to 200k-Hz and 125k-Hz respectively. The AR-200/AR-400 modules include a built-in 3mA excitation current to power the Integrated Electronics Piezo-Electric (IEPE) accelerometers and a 16-bit A/D converter.
The data acquired by the AR-200/AR-400 is saved on a Micro SD card that can be used for offline vibration analysis. A utility is also provided that can be installed on the Host PC so that the logger can be easily configured for different triggering modes, as well as changing the sampling rate, and scheduling the sampling time for various applications using the development tools. Consequently, the AR-200/AR-400 modules are recommended as your best choice for vibration monitoring and measurement.
