Description
Rotary Test Actuators
Rotary Test Actuators are heavy-duty torque generation devices that operate under precision servovalve control. When matched with servovalves, transducers, and closed-loop control electronics, Rotary Actuators are suited for testing materials, structures, and components.
The double-vane rotor design accommodates full force application through 100° of rotation. Matched reaction brackets, diaphragm flexures, and reaction bases allow you to create versatile test configurations that you can easily reconfigure. Available instrumentation options include angular displacement transducers, torque cells, and differential pressure cells.
