In-process testing demands speed, accuracy, and zero compromise. This fixture delivers all three.
◆ Accuracy That Keeps Production Moving
±5 arc-second positioning accuracy and ±3 arc-second repeatability across all three axes. Orthogonality within ±5 arc-seconds, intersection within a Φ0.5 mm sphere. These aren't just numbers—they're the difference between passing and failing on the production line.
◆ Speed Without Sacrificing Stability
Inner frame spins at 500°/s, middle at 400°/s, outer at 300°/s. Three-axis coordinated motion at 100°/s ties them together. Rate stability scales cleanly: 5×10⁻³ over 1°, 5×10⁻⁴ over 10°, 5×10⁻⁵ over 360°—clean data at every speed.
◆ Acceleration That Simulates Real-World Dynamics
Inner frame delivers 300°/s², middle 200°/s², outer 100°/s². Enough to replicate the rapid attitude changes and disturbances that MEMS sensors face in actual operation.
◆ Continuous Rotation Without Limits
360° on all three axes—no stops, no resets. Multi-turn profiling and extended testing proceed without interruption.
◆ Stainless Steel Foundation
Φ360 mm table with 0.02 mm flatness and 0.02 mm face runout. M6 mounting holes on 25 mm pitch. Your devices sit on a stable, repeatable surface that doesn't drift between test runs.
◆ Signal Integrity Through Continuous Rotation
30-channel slip ring—14 single-core at 3A, 16 twisted-pair shielded at 2A. Power and data flow uninterrupted, even as the fixture rotates through multiple turns.
◆ Automated Control for High Throughput
Computer-based status control with real-time data acquisition, processing, and display. RS232/RS422 interfaces drop seamlessly into existing production test systems.
◆ Built for the Factory Floor
120 kg package. 220 V ±10% / 50 Hz power. Operates from -10°C to 35°C and up to 80% RH. No special infrastructure required—just consistent, reliable testing shift after shift.
◆ Where This Fixture Excels
MEMS sensor in-process validation. Inertial measurement unit calibration. Gyroscope and accelerometer production testing. Quality assurance on the line. R&D when you need to scale up.
◆ The Takeaway
This fixture is designed for one job: testing MEMS sensors with accuracy and speed, in the environment where it matters most—production. It delivers laboratory-grade precision without sacrificing throughput.
