Introduction & Functions

1.    Product Introduction

The dual axis testing turntable consists of two main parts: a mechanical platform and a measurement and control system. It adopts a U-T or U-O structure and a precision mechanical shaft system, with position, velocity, and low-frequency sinusoidal oscillation motion. 

2.    Main Functions

It can provide accurate single axis and dual axis positioning and velocity reference for the tested load, and is used for static testing and calibration of inertial systems.
