    FAQ
    ❯

    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.

    ❯

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

    ❯

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