±0.05% FS shows up on every scanner datasheet worth reading. Getting that number under real test conditions is where products separate. Windtuner scanners keep it there through internal zero, full-scale, and multi-point calibration routines that run off the onboard pneumatic valve system—so nobody has to pull the unit offline to zero it. Thermal drift sits at ±0.001% FS per °C. That means if your test cell runs thirty degrees hotter by afternoon than it was at startup, your pressure readings stay put anyway.
Why Accuracy Matters More Than the Spec Sheet Says
Modular Design That Matches Real Test Setups
Test rigs don't come in standard sizes. A compressor rig might open with 32 taps and pick up another 16 when the second stage goes in. Windtuner pressure scanners use a modular architecture that grows with the test. The WTN-TX-M communication module connects units into a distributed network over TCP/IP and UDP, and the multi-channel connectors—a 2U15-channel WTN-TX-1501 and a 1U7-channel WTN-TX-0701—so adding channels doesn't mean rewiring the whole rig.
IEEE 1588V2 precision time protocol synchronizes every scanner in the network to a shared clock. When data from a 128-channel wall-tap array has to line up with probe traversal positions from the electric actuator system, time alignment is a hard requirement. At 500 Hz, even a two-millisecond slip between channels puts your flow maps out of register and throws stage efficiency calculations off. IEEE 1588V2 ships with every unit. It's not an add-on.
From Calibration Wind Tunnel to Production Floor
Every Windtuner pressure scanner goes through accredited validation before it ships. Windtuner operates the first private CNAS-accredited calibration wind tunnel laboratory in China, and Windtuner runs 10,000-hour endurance tests on prototypes there before anything goes to production. Each production scanner is validated in the same facility, and calibration certificates are available upon request. CE certification covers the full product line for clients working in EU-regulated test environments.
Compact enough to mount in tight rack space, the scanner also takes remote firmware updates, so it stays current without a factory return—useful on programs with hard delivery dates.
Pressure Scanners for the Full Test Chain
Windtuner designs the pressure scanner as one part of a measurement chain that includes pneumatic probes, electric actuators, and WindLabX measurement and control software. In practice, a test cell running a cascade wind tunnel experiment uses pressure scanners alongside five-hole probes and motion controllers to collect 3D flow field data fully automatically. A compressor test bench uses the same scanner hardware to feed stage-by-stage pressure maps into performance models. The same unit that measures total pressure at the engine inlet also feeds the WindLabX calibration module that runs metrological verification to JJG875-2019.
For teams building out a new test capability or replacing aging acquisition hardware, Windtuner pressure scanners deliver the accuracy, channel density, and synchronization that serious test campaigns require.
