Abstract
An assembly for monitoring torque applied to a control rod of an actuator, the control rod mounted within and rotational relative to a housing, the assembly comprising a torsional spring located between the control rod and the housing, and one or more sensors for monitoring angular displacement of the control rod relative to the housing as consequence of torque applied to the control rod transmitted through the torsional spring.
Claims14
An actuator assembly comprising:
- an actuator housing;
- an assembly for monitoring torque applied to a control rod of an actuator, the control rod mounted within and rotational relative to a housing, the assembly comprising:
- a torsional spring located between the control rod and the housing;
- and
- one or more sensors for monitoring angular displacement of the control rod relative to the housing as consequence of torque applied to the control rod transmitted through the torsional spring;
- wherein the assembly is mounted within the actuator housing, the control rod is arranged to move axially within and relative to the actuator housing, the control rod having a first end within the actuator housing and a second end extendible out of the actuator housing when the control rod moves relative to the actuator housing, the torsional spring provided at the first end of the control rod.
