TheBF350 is a high-precision resistance strain gauge sensor designed for accurate pressure and force measurement in structural applications. This sensor operates based on the principle of resistance change under mechanical deformation, making it suitable for detecting minute strains in materials such as metal beams, mechanical arms, or structural components. The BF350 strain gauge is widely used in load cells, tension sensors, and experimental mechanics.

Its compact design, sensitivity, and reliability make it ideal for DIY weight sensors, mechanical stress testing, or custom force measurement setups when combined with a Wheatstone bridge and an instrumentation amplifier like HX711.

Features of BF350 Strain Gauge Pressure Sensor:

1. High precision with stable resistance output
2. Measures mechanical strain and stress via resistance variation
3. Thin, lightweight, and easy to attach to surfaces
4. Ideal for steel structures, cantilever beams, or tension/compression sensors
5. Compatible with standard Wheatstone bridge circuits
6. Long life and excellent repeatability
