Various types of resistance materials have been developed for use in Gauge<\/i> – Gauge<\/i> wire and foil<\/i> , such as:<\/span> b.<\/span> Nichrome V is a nickel-chrome alloy used for the measurement of static strains up to 375 o<\/sup> C. with temperature compensation, this alloy can be used for static measurements up to 650 o<\/sup> C and dynamic measurements up to 1000 o<\/sup> C.<\/span><\/p>\n c.<\/span> Dynaloy is a nickel-iron alloy with a low Gauge Factor and high resistance to fatigue.<\/span> This material is used for dynamic strain measurements when high temperature sensitivity can be tolerated.<\/span><\/p>\n d.<\/span> Stabiloy is a modified nickel-chrome alloy with a summary of wide temperature compensation.<\/span> This gauge has excellent stability and cryogenic temperatures up to about 350 \u00b0<\/sup> C and good resistance to fatigue.<\/span><\/p>\n e.<\/span> Tungsten platinum alloys provide excellent stability and high resistance to fatigue at elevated temperatures.<\/span> This gauge is recommended for static test measurements up to 700 o<\/sup> C and dynamic measurements of 850 oC.<\/span><\/p>\n
\n a.<\/span> Constantan is a copper-nickel alloy with a low temperature coefficient.<\/span> Usually Constantan is found in Gauge used for dynamic strains, where strain level changes do not exceed \u00b1 1500 \u03bccm \/ cm.<\/span> The working temperature limit is from 10oC<\/sup> to 200oC<\/sup> .<\/span>
