strain gauges rosette

A rosette strain gauge integrates three separate measuring grids on one backing, oriented at set angles to capture the full strain tensor. Kingmach’s default rosettes use constantan foil on a polyimide carrier—a combination that handles civil engineering strain ranges and typical temperature swings without drifting. The grids are self-temperature-compensated for mild steel, though we keep variants for aluminum and stainless on the shelf too. Gauge lengths from 3–10 mm let you pick the spatial resolution that matches your material; coarser-grained concrete often calls for a longer grid to average out aggregate effects, while fine-grained metals can use the shorter options. For outdoor or embedded use, we supply versions with thicker encapsulation that resists moisture ingress. When a project requires surviving direct water exposure or alkaline concrete, we advise on protective coatings and leadwire strain relief—simple steps that make the difference between a data set and a dead channel. Our stock includes ASTM E837-compliant patterns for hole-drilling residual stress work, and we can adapt lead configurations and solder tabs to your installation method. Distribution centers in Europe and Asia shorten lead times for most standard models, and we keep a network of local bonding specialists who can take over site installation if needed.
