Is it true that the sensitivity of a gauge is its sensitivity line?
No, the sensitivity of a gauge refers to the ratio of the change in its output signal to the corresponding change in the input signal. The sensitivity limit refers to the minimum change in the input quantity that causes a change in the output at the starting point of the scale.
Sensitivity refers to the change in response divided by the change in stimulus. The sensitivity limit refers to the minimum change in the input quantity that causes a change in the output at the starting point of the scale. Their definitions are different. In fact, sensitivity needs to be defined in terms of the input change to be meaningful. It is difficult to compare different products and different definitions. More often, it can only serve as a concept. The sensitivity limit is actually the sensitivity defined in terms of the input and output (stimulus and response). Pretty practical. It can be said that the sensitivity limit is a specific expression of sensitivity. Additionally, there is a dead zone, which is a limited range that does not cause any noticeable changes. It can be said to be a specific expression of sensitivity.
Put simply, it is sensitivity: by how much does the output change when the input changes, which is a ratio. Detection limit: by how much must the input change for the output to change at all
