Abstract
The disclosure relates to an extensometer wherein the actuation of the contact arms is performed by a separate rotating bar so as to avoid or minimize placing active mechanics onto the arms. The rotating bar includes a spool about which a metal belt is wound. Rotating the bar, and hence the spool, in the desired direction pulls the metal belt which pulls a spring-loaded wedge with internal camming slots which urges the contact arms apart.
