Foil Resistance Strain Gauge BB Series

Product Introduction

Metal foil resistance strain gauges are the core sensitive chips of various strain sensors and measurement systems. Hualanhai's BB series strain gauge represents over 25 years of dedicated development and refinement in resistance strain gauge technology. Our foil strain gauge portfolio is divided into two primary categories: industrial precision resistance strain gauges and consumer-grade resistance strain gauges. The precision foil strain gauge variants utilize imported foil materials combined with rigorous heat treatment processes and advanced modified phenolic aldehyde substrates, enabling creep, hysteresis, and temperature performance characteristics to achieve within 0.007%. This exceptional accuracy makes our resistance strain gauge ideal for demanding industrial applications requiring precise strain measurement and sensor reliability.

Consumer electronics foil strain gauge offerings feature high production capacity and excellent cost-effectiveness, making them suitable for volume applications. In 2023, Hualanhai introduced advanced medium- and high-temperature strain gauge solutions specifically designed for operating environments up to 200°C, providing enhanced performance for high-temperature pressure sensors and demanding industrial applications. Our BB series strain gauge specifications include resistance ranges from 60 to 3000 ohms, sensitive grid sizes ranging from 0.5 to 100 mm, operational temperature ranges from -50 to 200°C, and daily production capacity exceeding one million units with most manufacturing processes achieving full or semi-automation levels.

The foil resistance strain gauge structure comprises four essential components: a substrate base, sensitive grid pattern, specialized adhesive system, and protective outer layer. These precision instruments are carefully etched from ultra-thin 0.005 mm metal foil, ensuring exceptional sensitivity and accuracy. The extremely thin sensitive grid design enables superior reflection of component surface deformation, guaranteeing high measurement accuracy in strain measurement applications. This precise construction is fundamental to the performance characteristics that make our BB series strain gauge the preferred choice for professionals requiring dependable strain measurement sensors.

Hualanhai offers customizable foil strain gauge solutions with resistance values from 60 to 5000 ohms, accommodating diverse application requirements and system integration needs. The BB series strain gauge finds extensive application across multiple industrial sectors, including precision weighing instruments, industrial force measurement systems, stress analysis testing equipment, high-temperature melt pressure sensors, and specialized strain measurement applications. Our commitment to delivering superior resistance strain gauge technology ensures that customers benefit from reliable, accurate, and durable strain measurement solutions that perform consistently across demanding operational environments and specialized applications.
