EF Series | High temperature miniature strain gauges
The EF series is a miniature foil strain gauge designed for high temperature application with polyimide resin as the backing materials and Ni-Cr alloy as grid materials. These gauges feature small grid pattern for strain measurement on PCB and surface mounted devices. The maximum operating temperature of these gauges are 300oC for single element gauges and 200oC for 2-element and 3-element rosette type gauges.
