Spectral Vibration Recorder

The MadgeTech Spectral Vibration Recorder (SVR) is a self contained device engineered to record acceleration data for spectral analysis of vibration and peaks. This device will record and time tag 3-axis vibrations and peaks to provide a history of shock/vibration conditions. It also records temperature once every sample period. The SVR measures and computes real-time spectral data using an FFT (Fast Fourier Transform) from 0 to 63.5 Hertz. To make efficient use of memory, the SVR only takes data when the (user preset) trigger level is exceeded. The basic data window is 2 seconds but the XYZ magnitude data can be averaged over longer sample periods of up to 2 hours.

A MadgeTech software and cable kit is required for operation. The easy-to-use MadgeTech software features enhanced tools like the use of engineering units, digital calibration, and automatic export to MS Excel.
