FAQ

Q1: What is the zero output of a sensor? ❯

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.

Q2: Why does bridge arm resistance change with temperature? ❯

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.

Q3: What is a temperature-compensating strain gauge? ❯

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.
