F series Foil strain gauge

f_list These gauges employ Cu-Ni alloy foil for the grid and special plastics for the backing.  A wide range of operating temperature from -196 to +150°C is possible.  The backing is color coded to identify the objective material for self-temperature compensation.  Strain gauges for stress concentration measurement and residual stress measurement are available in addition to general use gauges.  Leadwire integrated strain gauges are also available with various types of leadwires.  Strain gauges in this series can be supplied with option –F using lead-free solder.  (GOBLET gauges in this series use lead-free solder as standard specifications.)
