Smart overload control support products
PRODUCT INTRODUCTION
A rigid, strip-type dynamic weighing sensor manufactured with an Ω-shaped stepped structure, using piezoelectric quartz crystals as high-precision measuring sensing elements. It consists of piezoelectric quartz wafers, electrode plates and a special load-bearing device. Available in multiple lengths including 1m, 1.5m, 1.75m and 2m to suit lanes of different widths, it can be combined into traffic weighing sensors for various pavement sizes, achieving full coverage of the road surface and meeting dynamic weighing requirements.
