Product Description
Product Overview
The Ruijia Bridge Strain Gage Sensor is a precision three-axis 45° stacked strain gauge designed for structural health monitoring. With compact dimensions of 2.5×2.5mm, this temperature creep self-compensated sensor measures deformation in three directions (0°, 45°, and 90°) and serves as a reliable replacement for Japanese Republic brand products.

Installation Guidelines
For accurate stress testing results, follow these critical installation procedures:
- Environment temperature below 25°C and humidity below 60%RH
- Surface preparation with 300# sandpaper in 45° cross direction
- Thorough cleaning with organic solvents to remove dust
- Even glue application in one direction, preventing flow to strain gauge front
- Positioning with F4 film cover and thumb pressure for 1 minute
- 2-hour curing period before testing
- Proper lead and solder joint stress management
