EA-Series

Properly installed and wired EA-Series (polyimide-backed constantan foil) strain gages are capable of measuring maximum elongations in the range of 3% - 5%. While gage lengths of 1/8 in (3 mm) or longer will normally achieve 5%, shorter gage lengths may be limited to 3%. Since most structural materials (e.g., metals) yield well below this limit, the EA-Series is a popular choice for use in obtaining yield point information on these materials.
