Spectral Analysis Technology VSPECT The only solution for vibrating-wire measurements Eliminate noise spikes, false alarms Patented spectral analysis Have confidence in your measurements
Spectral Analysis Technology questions & quotes: 435.227.9120 VSPECT a is an innovative, patented technology that delivers the best measurement for vibrating wire sensors. VSPECT observes the incoming sensor signal, performs a Fourier transform and spectral analysis (transforming the Time Series into individual sinusoidal components in the Frequency Spectrum). The frequency is determined by identifying the largest signal in the acceptable range and disregarding unwanted noise. So…..

VSPECT observes the incoming sensor signal, performs a Fourier transform and spectral analysis (transforming the Time Series into individual sinusoidal components in the Frequency Spectrum). The frequency is determined by identifying the largest signal in the acceptable range and disregarding unwanted noise. VSPECT Outputs Include:
- Sensor Frequency (frequency of peak response)
- Amplitude (signal strength)
- Signal-to-Noise Ratio (measurement quality)
- Noise Fequency (largest observed noise)
- Decay Ratio (signal attenuation)
- Thermistor, if present (ohms or temperature) Lid screws (optional) Setup & Con/f_iguration The quick deploy guide is a reference tool outlining the setup process.
