3.3 Quality Control in Production
Operators perform point-of-use checks at various production stages such as magnet insertion, shaft assembly, and housing sealing. In-line functional tests measure signal output against reference standards. Torque-and-turn probes validate mechanical friction and center-return characteristics. Finished units undergo 100 percent visual inspection for cosmetic defects and a batch-sampling regime for performance testing, based on acceptable quality level (AQL) criteria agreed upon between supplier and distributor.
- Testing and Validation
4.1 Laboratory Testing Procedures
Pre-export validation is conducted on specialized test benches that simulate real-world steering conditions. Mechanical rigs impose angular cycles at varying speeds and torques, while environmental chambers test the sensors at temperature and humidity extremes. Electrical test stands apply voltage and current inputs to assess linearity, output stability, and fault-diagnosis responses. Detailed test plans covering thousands of cycles, vibration spectra, and shock pulses ensure each sensor meets or exceeds target specifications.
4.2 Endurance and Stress Testing
Endurance tests simulate extended vehicle operation. Sensors might be cycled through millions of angular rotations under continuous power to detect wear patterns and signal drift. Combined stress tests applying vibration, humidity, and temperature simultaneously reveal potential interactions between environmental factors. Results from these tests guide material upgrades or process optimizations to eliminate failure modes before full-scale production.
4.3 Field Trials and Pilot Programs
Before full-scale shipments, distributors and wholesalers often conduct pilot installations with select fleet operators or service centers. Field units experience actual road conditions, and telemetry systems capture real-time performance data. Feedback from technicians regarding installation ease, calibration stability, and troubleshooting is collected and used to inform final design tweaks and help refine user documentation.
