RSA-G2 I TECHNOLOGY
Transducer Mount
with Linear Slide
RSA-G2 Design Advantage
The RSA-G2 transducer is mounted to the instrument frame by a linear
slide and stepper motor allowing for independent vertical positioning.
Transducer motion is via a precision ground lead screw attached to a
micro-stepping motor by a rigid preloaded duplex bearing eliminating
backlash. A linear optical encoder is mounted directly between the
stationary frame and moving bracket for precision head positioning to
an accuracy of 0.1 !-1m.
Benefits of the independent transducer
positioning are:
•
Ease of clamp installation and sample loading
•
Compensation of sample expansion/contraction during experiments
•
Additional testing capabilities to large deformations such as strain rate
tests to pull samples until failure
