ABSTRACT:
A fluid actuator characterized by a linear variable differential transformer (LVDT) feedback mechanism driven off the actuator screw shaft for indicating actuator position. A protective clutch mechanism prevents possible damage to the LVDT or actuator in the event that the actuator stroke exceeds the design stroke of the LVDT.
