Ruijia 5mm Strain Gauge Sensor 120Ω Resistance High Precision Stress Testing Instrument -30°C to +80°C Range
Ruijia board measurement strainmeter high precision resistance strain gages are engineered for accurate stress testing applications. These customized strain gauge sensors deliver reliable performance in demanding industrial environments.
This series of strain gauges is specially designed for precision stress testing. Due to its small size, the following installation procedures must be followed to obtain accurate test results:
- Pasting environment temperature should be below 25°C with humidity lower than 60% RH
- Before pasting, polish the test component in a 45-degree cross direction using 300# sandpaper, with polished area exceeding strain gauge dimensions
- Clean surface with organic solvents to remove dust and allow quick evaporation
- Apply glue evenly in one direction to both the measured part and strain gauge back, preventing flow to the front
- After positioning, cover with clean F4 film, press with thumb for 1 minute, then remove film after pressure release
- Allow 2 hours curing time before testing
- Ensure no stress between leads and solder joints during all operations to prevent joint failure or wire breakage
