Foil Resistance Strain Gauge Sensor – Precision Load & Pressure Measurement

The Strain Gauge Foil Resistance Sensor is a high-accuracy device designed to measure mechanical deformation, load, or pressure by detecting tiny changes in resistance. Utilizing foil strain gauge technology, it converts applied force or stress into an electrical signal proportional to the strain.

This sensor is widely used in load cells, torque measurement systems, pressure transducers, structural testing, robotics, and laboratory experiments, providing reliable and repeatable measurements in both static and dynamic applications. Its compact foil design allows integration into tight spaces and ensures minimal interference with the mechanical system being tested.
