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. Rated Resistance: 350-1000 Ohm Various creep codes available Used in applications where shear load cell or torque force is measured. Single measuring grid on a backing, usually directed at a 45°.

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°) 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).
3. Shear/Torque Foil Gauges
Design: Diagonal grid pattern optimized for shear strain measurement.
Torque sensors (rotating shafts in engines and robotics).
Force transducers (twisting/bending applications).
4. Diaphragm (Planar) Foil Gauges Design:
Pressure Sensors (fluid/gas pressure measurement).
Medical Devices (blood pressure sensors, respiratory monitors).
5. Full-Bridge Foil Gauges (Pre-Installed Wheatstone Bridge)
Design: Four active strain gauges in a Wheatstone bridge configuration for high sensitivity & temperature compensation.
Used in:
High-Precision Load Cells (industrial weighing, aerospace testing).
Strain-based accelerometers (vibration sensors).
