3FDT400-C three-axis turntable
The three-axis turntable is a specialized precision equipment developed for research, testing, production debugging, and maintenance calibration of fiber optic gyroscopes, MEMS gyroscopes, and IMUs. It is mainly used for speed and position function testing and has the characteristics of stable performance, reliable operation, simple operation, easy portability, and low purchase cost. The equipment can also be used for testing other inertial components and devices.
The turntable consists of several parts, including the mechanical platform, measurement and control system, and software.
The external dimensions of the platform are approximately 900mm × 650mm × 1100mm; the total weight is not more than 400kg.
