Primary Strain and Stress Sensors

At Strain and Stress Measurement Devices, we provide a comprehensive line of sensors that offer real-time strain and stress monitoring capabilities for both static and dynamic applications. Each sensor type is engineered with industry-leading precision and designed to perform in the most challenging industrial and environmental conditions.

Foil Strain Gauges

These are the most widely used sensors for structural testing, offering stable and accurate readings. Made from metallic foil grids bonded to a backing material, foil strain gauges are ideal for detecting axial, bending, and torsional strains in metals, composites, and concrete.

Semiconductor Strain Gauges

Providing higher sensitivity than traditional foil gauges, semiconductor strain sensors are used when fine-resolution strain measurement is critical. Their piezoresistive properties enable detection of small stress variations, making them ideal for medical devices, aerospace components, and precision instruments.

Fiber Bragg Grating (FBG) Strain Sensors

FBG sensors use fiber-optic technology to measure strain and temperature changes across long distances. Immune to electromagnetic interference and ideal for harsh or hazardous environments, these sensors are particularly effective in large infrastructure like bridges, tunnels, and wind turbines.

Piezoelectric Strain Sensors

Utilizing the piezoelectric effect, these sensors generate electric charges under mechanical stress. They are excellent for dynamic applications such as vibration monitoring, fatigue testing, and impact analysis in automotive, aerospace, and mechanical testing environments.

Vibrating Wire Strain Gauges

Common in geotechnical and structural health monitoring, these sensors measure tension based on changes in wire vibration frequency. Their durability and long-term stability make them ideal for bridges, dams, tunnels, and other civil infrastructure projects.

Capacitive Strain Sensors

These sensors measure strain by detecting changes in capacitance between two plates. Offering low noise and high resolution, they are useful in applications requiring precise micro-strain measurement, including R&D labs, MEMS devices, and precision mechanics.
