FAQ

Q1: What is a strain gauge? ❯

A strain gauge is a sensor used to measure the amount of strain or deformation in an object under stress. It converts mechanical deformation into a change in electrical resistance.

Q2: What are the common types of strain gauges? ❯

Common types include quarter bridge, half bridge, and full bridge configurations, as well as foil, wire, and semiconductor types.

Q3: What does the resistance value (e.g., 350Ω, 1000Ω) mean? ❯

It indicates the electrical resistance of the strain gauge grid. Higher resistance reduces current and temperature rise, while 350Ω is widely used standard.
