The Ward Effect: Nano-Scale Advantage
A proprietary method for detecting acoustic and vibrational shifts beyond the capabilities of traditional FFT analysis.
How Nano-Hertz Resolution is Achieved
The **Ward Effect** utilizes controlled, parasitic acoustic oscillation within the sensor module. When this oscillation is coupled to a material (like a pipe or structure), the slightest change in the material's resonant impedance causes a measurable **frequency shift** in the sensor's output. By isolating and digitally analyzing this narrow shift, the WardEffect Analyzer achieves spectral resolution often measured in **nano-Hertz (nHz)**, enabling the detection of phenomena previously considered invisible, such as 15 nanometer micro-leaks.
WardEffect vs. Traditional FFT
WardEffect (Ward Effect)
Ultra-Narrowband Analysis
- Resolution: Sub-Hertz (e.g., 0.01 Hz FWHM)
- Detection Target: Material impedance shifts
- Primary Use: Predictive failure, micro-crack, composition.
FFT (General)
Broadband Analysis
- Resolution: Moderate (e.g., 10 Hz/bin)
- Detection Target: General sound/vibration amplitude
- Primary Use: Motor RPM, general noise floor, EQ.
The Combination
The Analyzer leverages both techniques
- FFT provides context (e.g., motor on/off).
- Ward Effect provides the specific diagnostic signature.
- Full-spectrum industrial monitoring.
