Measurement Accuracy and Resolution – The Foundation of Every Experiment
Accuracy and resolution define the credibility of experimental results. Low accuracy or insufficient resolution can lead to significant pressure field reconstruction errors, which distort the computation of aerodynamic parameters. Windtuner pressure scanners deliver a system accuracy of ±0.05% FS, ensuring repeatability and comparability in both scientific and aerospace-grade tests. What matters most is that accurate scanners catch subtle yet critical pressure fluctuations, which are otherwise neglected. These deviations that go unnoticed could have mislead aerodynamic optimization or verification, especially under low differential pressure conditions.
For instance, in aerodynamic testing, a systemic bias in pressure readings could misdirect wing shape optimization, resulting in substandard performance or safety risks during flight. In gas turbine experiments, pressure errors may obscure local backflow or shockwave positions, compromising lifetime assessment and failure prediction.
Sampling Frequency and Bandwidth – Restoring Dynamic Reality
Sampling frequency and sensor bandwidth determine how effectively a scanner can capture transient flow field features. Dynamic phenomena such as turbulence pulsation, blade-passing disturbances, and combustion pressure oscillations require high bandwidth and per-channel sampling rates that reach hundreds to over a thousand hertz. However, a high sampling rate does not necessarily imply wide bandwidth—the pneumatic and structural dynamics of sensors also limit measurable frequencies. Moreover, scanners using channel multiplexing may suffer from aliasing and timing issues if not properly designed or calibrated. Insufficient bandwidth or sampling misconfiguration can suppress or distort transient pulses, leading to flawed analysis of unsteady aerodynamic behaviors.
For example, during synchronous blade excitation tests in turbomachinery, excitation amplitude and frequency may be underestimated if high-frequency pressure pulsations are not successfully captured, directly impacting fatigue life predictions.
Counting Channels and Capturing the Full Picture
Complex experimental setups such as wind tunnel models or compressor cascades often require dozens to hundreds of pressure measurement points. A limited channel count forces users to deploy multiple scanners or rerun experiments, lowering efficiency and inflating costs. Modern multi-channel systems—such as Windtuner’s Ethernet Intelligent Pressure Scanner with 16-channel modular design—can be flexibly expanded to 32, 64, or even 128 channels, ensuring synchronous data collection and high system efficiency.
Pressure Range – Matching Every Testing Condition
Different testing scenarios demand distinct pressure ranges, from low-pressure aerodynamic models to high-pressure combustion environments. Incorrect range selection can lead to saturation, degraded accuracy, or even sensor failure. Windtuner pressure scanners provide a wide variety of pressure ranges and customizable configurations, supporting both low differential and high static pressure applications.
On the other hand, when it comes to inaccuracy, falling short of any of these parameters, we face such consequences:
Data distortion:Loss of crucial flow field features such as transient peaks, vortex separations, and disturbances.
Misguided design:Flawed aerodynamic optimization or structure redesigns based on unreliable data.
Escalating costs:Repeated tests, extended downtime, and manual recalibration.
Safety risks:Performance deviations in high-risk environments such as flight or turbine operations.
In short, performance indicators are the foundation of risk control and experimental efficiency and cannot in any way be dismissed as simple technical indicators.
