KFW Series Waterproof Foil Strain Gauges
The KFW series foil strain gauges have the surface covered with a special resin for waterproof. The waterproof structure enables these gauges to serve for outdoor or underwater measurement merely by being bonded to measuring objects. The insulation resistance shows virtually no deterioration even after 100 hours of use under an underwaterpressure of approximately 10MPa.In addition, the covering resin is flexible enough to enable easy bonding to curved surfaces.
When ordering, suffix the lead wire cable code (See table above) to the model number with a space in between. E.g. KFW-5-120-C1-11 L2M2R for the gauge with a vinyl-coated flat 2-wire cable 2 m long KFW-5-120-D17-11 L5M3S for the gauge with a vinyl-coated flat 3-wire cable 5 m long.

Notes on pre-attached lead wire cables:
- Standard color of the 2-wire cable pre-attached to uniaxial gauges is red (R). If desired, a white, green, yellow or black cable can be pre-attached.
- Standard 3-wire cable pre-attached to uniaxial gauges has red stripes (R). If desired, the red stripes can be changed to blue or yellow stripes.
- In the case of a biaxial gauge, 2-wire cables are color-coded with red and white stripes for 0° and 90°, respectively and 3-wire cables, with red and yellow stripes for 0° and 90°, respectively.
- In the case of a triaxial gauge, 2-wire cables are color-coded with red, white and green stripes for 0°, 90°, and 45°, respectively and 3-wire cables, with red, yellow and blue stripes for 0°, 90°, and 45°, respectively.
