Product Description
GCF120-1CB Three-Axis Strain Gauge Sensor
The GCF120-1CB series is a precision three-axis 45° stacked strain gauge designed for multi-directional deformation measurement. This compact 4.0×4.0mm sensor measures deformation in three directions: 0°, 45°, and 90°, making it ideal for stress analysis on metal components and PCB boards.
Key Features
- Three-axis measurement capability (0°, 45°, 90°)
- Temperature and creep self-compensation
- Compact 4.0×4.0mm dimensions
- Compatible replacement for Japanese Republic brand products
- High fatigue lifetime exceeding 10,000,000 cycles
Installation Guidelines
For optimal performance and accurate test results, follow these installation procedures:
- Environment: Temperature below 25°C, humidity below 60% RH
- Surface Preparation: Polish with 300# sandpaper in 45° cross direction, clean with organic solvents
- Adhesive Application: Apply glue evenly in one direction to both surfaces
- Positioning: Cover with F4 film, apply thumb pressure for 1 minute
- Curing Time: Allow 2 hours before testing
- Lead Handling: Avoid stress on leads and solder joints
