The ring-type load cell is a high-precision weighing component with a central aperture and ring-shaped structure. It converts pressure or tension into electrical signals for weight measurement. Due to its compact design and strong resistance to off-center loading, it is widely used in scenarios requiring limited installation space and stable measurement performance.
Working principle:
When a weight (or pressure, tension) acts on the ring-shaped sensor, the ring-shaped elastic body undergoes slight deformation, causing the strain gauge to stretch or compress. The change in the strain gauge’s resistance generates a weak voltage signal (typically at the millivolt level) from the Wheatstone bridge. This signal is amplified by an amplifier and then transmitted to the weighing instrument or controller, ultimately converting into a visual weight reading.

Fonction:
Strong resistance to offloading
The ring structure ensures a more even distribution of stress points, reducing the impact on measurement accuracy even when the load is slightly offset from the center (off-center loading). It is suitable for scenarios where the load cannot be guaranteed to be absolutely centered (e.g., rotary weighbridges, suspended weighing).

It is suitable for scenarios where the load cannot be guaranteed to be absolutely centered (e.g., rotary weighbridges, suspended weighing).
Compact installation space
The ring design does not require additional large installation space, as the central opening allows direct passage of bolts, drive shafts, or cables, making it particularly suitable for scenarios with limited internal space (such as automated production lines or small weighing devices).

Wide measurement range
The measuring range can be adjusted from a few kilograms (e.g., for small equipment weighing) to hundreds of tons (e.g., for large industrial weighing), achieved by modifying the material thickness and aperture size of the ring-shaped elastic body to accommodate different ranges.

High stability
The mechanical properties of metal elastomers are stable, with excellent deformation recovery after prolonged stress. Additionally, their ring structure provides strong damping capabilities against vibration and impact, making them suitable for long-term continuous operation in industrial environments.
