Narrow-strip load cells

PRODUCT INTRODUCTION

Narrow-strip load cells are sensors designed for dynamic weighing. Their core principle is that force-induced deformation of elastic elements converts pressure into electrical signals for measurement. Their key advantages include high precision (±5% dynamic weighing accuracy), long service life (low stress and small deformation), and easy installation.
Made of high-quality alloy steel with precision machining, these sensors feature high overload resistance and can adapt to various complex road conditions, including bridge decks and curves. Suitable for high-speed pre-weighing systems, they enable dynamic weighing of vehicles traveling at speeds ranging from 0.5 to 100 km/h, and are widely used in highway toll collection, overloading and over-limit control, and other fields.
