Introduction
Functional Description
The AHX800 High Elongation Extensometer is designed to operate at
temperatures from 5 to 40°C. The key part of the extensometer is an optical
encoder. The movement of the extensometer arms makes the optical encoder
rotate. The encoder send pulses to a circuit where the pulses are converted for use
by the controller.
Frame Assembly (all other components)
The two arms of the extensometer are attached to the specimen. A cable/pulley
mechanism allows the arms to track the elongation of the specimen. The cable
movement is detected by an encoder. The encoder sends pulses to a circuit board
that converts the pulses to determine the exact displacement of the extensometer
arms.
The high elongation extensometer can rotate 90° to minimize the required
working space.
