These are foil strain gauges designed for measurement on composite materials. These strain gauges have specially designed grid pattern to reduce the stiffening effect of strain gauge on the specimen. Self-temperature-compensation is available for materials having coefficient of thermal expansion of 3, 5 or 8 ×10-6 strain/°C, which makes these strain gauges suited for measurement on ceramic, carbon or composite materials.
New series of strain gauges named GOBLET are added to this series. They are compliant with RoHS 2 Directive 2011/65/EU and supplied with CE marking. Even though lead-free solder is used in the GOBLET gauges, they show better performance than conventional strain gauges owing to the adoption of unique gauge pattern. Extension leadwires with CE marking are also available.
