In modern industrial automation and mechanical control systems, compact force sensors are widely used for load monitoring, assembly control, and force measurement applications. Among different structural designs, ring-shaped force sensors are commonly selected for systems where force is transferred directly through bolts, shafts, or fastening structures.

The Ring-Shaped Force Sensor (LFC-68), developed by Shenzhen Ligent Sensor Tech Co., Ltd., is designed with a compact ring structure that supports direct force-path installation while maintaining stable measurement performance in mechanical assemblies.

Its sensing performance is mainly based on four important structural components: the ring-shaped elastic body, strain gauge arrangement, central bolt-through mounting structure, and protective sealing housing.

Ring-Shaped Elastic Body Structure

The core sensing structure of the LFC-68 is the ring-shaped elastic body, which functions as the primary force-sensitive component.

When external force is applied, the elastic body undergoes slight elastic deformation corresponding to the load magnitude. The ring geometry helps distribute force evenly throughout the structure, supporting stable deformation behavior during operation.

Compared with some traditional force sensor structures, the ring-shaped design is more suitable for compact installation environments where force transmission occurs through a central mechanical connection point.

This structural configuration also helps improve integration flexibility in industrial equipment and automated systems.

Strain Gauge Measurement Design

The sensor uses strain gauges mounted at carefully selected positions on the elastic body surface.

These installation points are determined according to the deformation characteristics of the ring structure under load conditions. As the elastic body deforms, the strain gauges detect microscopic strain changes and convert them into electrical signal output.

The signal can then be processed by control or monitoring systems for force measurement and load analysis.

Stable strain gauge positioning is important for maintaining consistent sensor response and measurement repeatability during long-term operation.

Central Bolt-Through Installation Structure

One of the main design features of the LFC-68 ring-shaped force sensor is its central mounting hole, also known as a bolt-through structure.

This design allows the sensor to be installed directly around bolts, shafts, or fastening components within the mechanical force transmission path.

Because force passes directly through the center of the sensor structure, the sensor can be integrated into compact assemblies without requiring large additional mounting space.

This inline installation method is commonly used in:

• Mechanical fastening systems

• Automated assembly equipment

• Industrial press systems

• Clamping force monitoring applications

• Shaft and bolt load measurement systems

The bolt-through design also simplifies installation and supports structural integration in limited-space applications.

Protective Housing and Sealing Structure

Industrial environments often expose sensors to dust, moisture, vibration, and mechanical impact.

To improve operational stability, the LFC-68 is designed with a protective outer housing and sealing structure that helps protect internal sensing components during operation.

The sealing design supports stable use in industrial environments while helping reduce the influence of external contamination on sensor performance.

In addition to environmental protection, the housing structure also provides mechanical protection during installation and long-term operation.

Advantages of Ring-Shaped Force Sensor Design

Compared with some conventional force sensor structures, ring-shaped force sensors offer several structural advantages for compact mechanical systems:

• Direct force-path installation

• Compact structural footprint

• Easy integration around bolts or shafts

• Stable load distribution characteristics

• Simplified inline installation

• Suitable for limited-space mechanical assemblies

Because of these advantages, ring-type load cells are increasingly used in automation equipment, industrial machinery, fastening systems, and force monitoring applications.

Typical Application Areas

Ring-shaped force sensors are commonly integrated into systems requiring compact force measurement and stable mechanical installation, including:

• Industrial automation equipment

• Mechanical assembly systems

• Press and clamping equipment

• Bolt preload monitoring

• Robotics and motion control systems

• Load monitoring structures

• Precision industrial machinery

Their compact structure makes them suitable for applications where traditional large load cells may not fit efficiently.

Conclusion

The LFC-68 Ring-Shaped Force Sensor combines a ring-shaped elastic body, strain gauge sensing technology, bolt-through mounting structure, and protective sealing design into a compact force measurement solution.

These structural features allow stable force transmission measurement while supporting efficient integration into modern industrial and automation systems.

Developed by Shenzhen Ligent Sensor Tech Co., Ltd., the sensor is designed for applications requiring compact installation, direct force-path measurement, and reliable structural performance in industrial environments.
