General-purpose Foil Strain Gages KFG

General-purpose Foil Strain Gages KFG -8 General-purpose Foil Strain Gages in KFG Series Grid width Grid length (Gage length) Base length The KFG series gages use polyimide resin for the base approx. μm thick, ensuring excellent flexibility. Besides indoor measurement, the outstanding moisture resistance lets them effectively perform outdoor measurement. Unless directly exposed to water drop, no coating treatment is required. Applicable Adhesives and Operating Temperature Range after Curing CC-A: -96 to 0 C ( 0 to 80 C with vinyl-coated cable attached) CC-: -0 to 0 C ( 0 to 80 C with vinyl-coated cable attached) CC-6: -0 to 00 C ( 0 to 80 C with vinyl-coated cable attached) EP-40: - to 0 C ( 0 to 80 C with vinyl-coated cable attached) PC-600: -96 to 0 C ( 0 to 80 C with vinyl-coated cable attached) base width Gage lead Notes on pre-attached lead wire cables Standard color of the -wire cable pre-attached to uniaxial gages is red (R). If desired, a white, green, yellow or black cable can be pre-attached. Standard -wire cable pre-attached to uniaxial gages has red stripes. If desired, the red stripes can be changed to blue or yellow stripes. In the case of a triaxial gage, -wire cables are color-coded with red, white and green stripes for 0, and, respectively and -wire cables, with red, yellow and blue stripes for 0, and, respectively. The letter code is S in common.
