Bestech Australia have introduced F-series strain gauges from TML. These strain gauges are used for physical force measurements in mechanical, marine, aircraft and civil engineering and in fields of architecture, automobiles, and medical science.
The general purpose F-series strain gauges consist of photo-etched metallic resistance foil, together with an electrical insulation base and a set of gauge leads.
These strain gauges employ specially controlled alloy foils, which are 0.003 to 0.007 mm thick. The grid is precision-etched using advanced technology, and makes use of a thin epoxy backing, which exhibits better electrical insulation performance. A gauge length of 0.2mm and a stress concentration measurement gauge are available in this series.
F-series strain gauges can operate in temperatures of between -20 and 80°C. The element material is Cu-Ni alloy, and applicable bonding adhesives include CN, P-2 and EB-2. The strain limit in these gauges is 3% (30000 x 10-6) and fatigue life at room temperature is 1x106.F-series strain gauges are applicable on metal, glass and ceramics, giving it variability in use. The leadwire-integrated F series has a pre-attached vinyl lead wire to the F series strain gauges.
