Composite Strain Gauge
UBF series Composite strain gauge
- BF series Composite 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.
