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.
