The HaiboSensor type foil strain gauge is a small, flexible sensor made of thin metal foil that measures how much an object stretches or bends by detecting changes in electrical resistance when force is applied, commonly used in scales, vehicles, buildings, and medical devices to monitor stress and strain. Foil Constantan or karma-measuring grid material. The sensitive grid is very thin and can better reflect the deformation of the component surface. Therefore, the measurement accuracy is high. A 60-5000 ohm strain gauge can be customized; it is widely used in various weighing instruments, industrial force measurement, stress analysis and testing, high-temperature melt pressure sensors, and so on.
Foil Constantan or karma-measuring grid material.
Rated Resistance: 350 – 2000
Various creep codes available
Used in applications where shear load cell or torque force is measured.
Single measuring grid on a backing, usually directed into a 45° angle
Silver or enameled wires and cables
1. Single-Linear (Uniaxial) Foil Gauges
Load Cells (beam-type, bending applications).
Stress Analysis (unidirectional force testing in materials).
Structural Monitoring (e.g., axial strain in bridges, trusses
2. Rosette (Multi-Axial) Foil Gauges
Design: Multiple grids arranged at specific angles (e.g., 0°/45°/90° or 0°/60°/120° 200°) to measure complex strain fields.
Types & Applications:
90° (Two-Element) Rosette—Measures biaxial strain (e.g., pressure vessels).
45° or 60° (Three-Element) Rosette—Determines principal strains in sheet metal, automotive components, and aircraft wings.
T-Type Rosette—Used in torque sensors (measuring shear strain in shafts).
200° (Three-Element) Rosette— industrial force measurement, stress analysis and testing, and high-temperature melt pressure sensors.
3. Shear/Torque Foil Gauges
