DT850 2D turntable
The two-dimensional macro stepper turntable has two degrees of freedom in motion, namely the azimuth axis (X) and the elevation axis (Y), and is a table type two-dimensional precision testing equipment. Mainly used for testing and calibration of inertial devices and components such as fiber optic gyroscopes and inertial measurement units (IMUs).
Specially designed for high-precision motion control in extreme environments. The two-dimensional macro step diameter turntable can maintain excellent angular position, angular velocity control accuracy, and reliability within a wide temperature range of -55 ℃ to+80 ℃ while bearing a load of 160kg, solving the problem of precision testing under harsh working conditions.
