Abstract:An insight into strain gauge telemetry techniques explaining why telemetry can offer interesting advantages over conventional strain gauge systems. The difference between a.c. strain gauge measurements and analogue to digital conversion followed by a.c. transmission is discussed together with the importance of a.c. transmission in the avoidance of drifts and parasitic effects applicable to d.c. systems.
A comparison between frequency modulation (FM) and time or pulse duration modulation (PDM) explains why PDM … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
