    FAQ
    ❯

    Zero output is the potential difference between two points on the sensor's output terminals and is primarily determined by the matching of adjacent bridge arm resistors. When the bridge arm resistors are not perfectly balanced, a zero voltage will be generated even without an external force.

    ❯

    Bridge arm resistance changes with temperature because the resistance of the strain gauge material fluctuates with temperature, leading to bridge arm mismatch and resulting in zero drift.

    ❯

    A temperature-compensating strain gauge reduces the effects of thermal output during temperature changes, minimizing resistance changes and thus reducing zero drift. While it cannot completely eliminate thermal output, it is much more stable than a conventional strain gauge.

    half bridge strain gauge is a solid option
    Got these for building a custom load measurement setup. The half bridge strain gauge arrived well packed and the quality looked good. Soldering the leads took some patience, but the connection was fine after testing. It worked nicely with the bridge circuit and gave consistent results during repeated loading tests. A good choice for this kind of work.
