Omega Engineering”sOM-CP-SVR101 Spectral Vibration Recorder (SVR) is a self-containeddevice engineered to record acceleration data for spectral analysis ofvibration and peaks. This device will record and time tag three-axisvibrations and peaks to provide a history of shock/vibrationconditions. It also records temperature once every sample period. Thedevice measures and computes real-time spectral data using an FFT (FastFourier Transform). To make efficient use of memory, the device onlytakes data when the (user preset) trigger level is exceeded.
