Foil Type Strain Gauge
UBF Series Composite Strain Gauge
These are strain gauges developed for measurement on composite materials, and are designed with a proprietary special grid pattern to reduce the stiffening effect of the strain gauges. Owing to the development of gauge backing with better compliance, the number of repetitions in thermal cycling tests and creep characteristics have been significantly improved compared to conventional strain gauges (Tokyo Measuring Instruments Laboratory comparison). Optional (-F) lead-free solder specifications are also available.

BF Series Composite Strain Gauge
BF series composite strain gauges are developed for measurement on composite materials, and are designed with a proprietary special grid pattern to reduce the stiffening effect of the strain gauges. Models are available for materials with coefficients of thermal expansion of 3 × 10-6/℃, 5 × 10-6/℃、8 × 10-6/℃ allowing use with ceramics, carbon, composite materials, etc.
A new series of strain gauges bearing the CE mark, GOBLET, has been added. This CE-compliant series of products is compliant with RoHS directives. These gauges exceed the capabilities of conventional strain gauges with lead-free soldering as well as a unique tab design. CE-compliant extension lead wires are also available.
