General-purpose Foil Strain Gages

The KFGS series gages are engineered to deliver exceptional performance in a wide range of environments, making them an ideal choice for diverse measurement needs.

The KFGS series gages use polyimide resin for the base that is approx.14 μm thick. It ensures excellent ﬂexibility. The outstanding moisture proof enables the KFGS gages to operate effectively both indoors and outdoors. Unless directly exposed to water droplets, no coating treatment is required.
