Further design improvements over traditional strain gage types include smaller and tighter grid-resistance tolerances, improved gage-to-gage repeatability, and enhanced measurement stability. All enhancements are implemented via a fully optimized fabrication process, incorporating the very latest in tooling, methods, and equipment. As a result, the prototype design and manufacturing of anywhere from a single strain gage piece up to OEM volumes may be easily accommodated, with uniform high quality and competitive lead times.
The Micro-Measurements Advanced Sensors Technology product portfolio includes linear, shear and circular gages, arranged as individual, half-bridge and full-bridge configurations, in ranges from 350 Ω to 20 kΩ, with added flexibility in mounting options. The technology improves grid-to-grid tolerances and matching over traditional strain gage manufacturing techniques, enabling better sensor performance. In the case of full-bridge gage configurations, all intra-bridge connections are integrated directly into the pattern itself, eliminating the need for traditional intra-bridge soldering. The addition of gold-plated solder pads improves solder-joint reliability, while reducing the risks of solder pad oxidation prior to lead wire attachment. These processes further ensure the close matching of grid-to-grid thermal characteristics and bridge circuit thermal output cancellation specifications, both of which are essential to strain gage measurement accuracy.
