Strain Gauge Bending Sensor Module Y3 Weighing Amplifier Module

Strain Gauge Bending Sensor Module Y3 – BF350-3AA Weighing Amplifier

The Strain Gauge Bending Sensor Module Y3 is designed for precise force, weight, and pressure measurement. Built around the BF350-3AA strain gauge, it comes with an onboard amplifier and zero potentiometer for fine-tuning the output signal. This module is widely used in electronic weighing scales, force sensors, and industrial testing applications.

A strain gauge changes its electrical resistance when subjected to force, tension, or bending. By measuring this change, the module converts mechanical stress into an analog electrical output. It operates on the principle of electrical conductance, where the geometry of the conductor changes (becomes narrower and longer) when stretched within its elastic limits.
