1270VS Series Single Axis Rate Table

The Model 1270VS Rate Table is used for the testing and calibration of sensors and gyroscopic instruments which require a precise and accurate angular velocity. The 1270VS Rate Table is an automated, variable-speed table with a 21,600:1 speed range.

The front panel controls and liquid crystal display give the user full digital rate entry with multiple rate presets. The front panel consists of a power switch, LCD display, and four keys: run/menu, increase, decrease, and enter.

Full computer-controlled automation can be accomplished with an RS-232 (standard) or IEEE-488 (optional) interface. The closed-loop motion control system consists of a DC servo gearmotor, a controller, and an optical encoder. The encoder is located on the high-speed shaft of the gearmotor to provide high-resolution feedback for precise speed regulation. A gear train with electric clutches is used to select four different ranges.

The rate table can turn in both clockwise and counter-clockwise directions. Clutches protect the gear train if large forces are applied to the tabletop. A four-point contact bearing is used to resist axial, radial, and moment loads while providing smooth rotation. Slip rings and a vacuum line are also standard features of the test table.

The Single-Axis Product Selection Matrix allows you to easily compare the primary specifications for each of the single-axis table systems. Please note that almost every system that Ideal manufactures can be customized to meet a customer’s specific requirements.
