PRODUCT OVERVIEW

Two-axis inertial testing.Temperature-controlled environment.

ACCUDYNA describes the FDA-222-TCC-ECO as a multi-class, two-axis rate table intended for development, in-process testing, calibration, and final inspection of inertial components and instruments.

The catalog specifically identifies high-precision MEMS sensors at FOG performance level, medium IMUs, and MEMS-class IRUs among the intended test articles.

The model combines an inner and outer axis with a liquid carbon dioxide (LCO2) temperature chamber. The outer axis includes a stow lock to facilitate safe loading and unloading of the UUT.

The manufacturer highlights a user-friendly HMI in a 4U control rack-mount, a compact and cost-effective two-axis architecture, and direct-drive brushed torque motors.
