3.1 Vibrating wire bulb

A sensor for measuring the stress of a steel bar using the natural frequency of a vibrating wire.

3.2 Resolution

In the measurement range, the minimum value of the measured value measured by the bar is expressed as a percentage of the full-scale output.

3.3 Lag hysteresis

Backlash

Hysteresis

When the input amount is full-scale change, for the same input, the positive and the reverse stroke of the steel bar are the maximum of the actual average characteristic curve output […]
