Operating temperature range extends from -50°C to 200°C, providing versatility across industrial applications. Our manufacturing capacity reaches one million pieces daily with most production processes achieving full automation or semi-automated efficiency.

Structural Composition and Design

Each foil resistance strain gauge comprises four critical components: the substrate, sensitive grid, adhesive layer, and protective coating. The sensitive grid is precision-etched from exceptionally thin 0.005mm metal foil through advanced microfabrication techniques. This ultra-thin construction enables superior sensitivity and response, allowing the foil strain gauge to accurately capture even minimal surface deformations. The refined geometry of the sensitive grid ensures precise reflection of component surface movement, directly contributing to high measurement accuracy and reliable sensor performance in critical applications.
