Metal Debris Detection System SYAD100

High-Reliability Calibration and Verification Platform for Metal Debris Detection Systems under Temperature ––– Vibration Coupled Environments

Product Description

I. Product Overview
The SYAD100 Metal Debris Detection System is a high-precision calibration and environmental verification platform developed for aerospace, propulsion, and industrial transmission systems. It is engineered to perform functional verification, ratiometric calibration, and performance characterization of metal debris sensor subsystems under extreme thermal conditions.
The system enables quantitative assessment of sensor signal conditioning circuits, including evaluation of temperature-induced offset drift, gain drift, and noise variation, ensuring reliable sensor operation under complex operational environments.
This system adopts an innovative “remote drive with flexible shaft transmission” design, providing thermal decoupling between the drive system and high-temperature chamber environment. This architecture prevents thermal degradation of motor windings and power drive electronics, guaranteeing long-term stable operation within –55°C to +180°C.
The mechanical design is vibration-test compatible, supporting combined temperature–vibration environmental simulations.
