Accuracy

Accuracy is one of the most important factors to consider when choosing a digital gauge. Digital gauges are generally more accurate than analog gauges, as they are not subject to mechanical errors. This is because digital gauges use electronic sensors to measure the physical property being measured, and then convert that signal into a digital reading. Analog gauges, on the other hand, rely on mechanical components to measure the physical property being measured, which can be less accurate.

• Linearity: Linearity refers to the ability of a digital gauge to measure a physical property over its entire range with the same degree of accuracy. A linear gauge will produce a straight line when its output is plotted against the input.
• Hysteresis: Hysteresis refers to the difference in the output of a digital gauge when the input is increasing versus decreasing. A gauge with low hysteresis will have a small difference between its output when the input is increasing and decreasing.
• Repeatability: Repeatability refers to the ability of a digital gauge to produce the same output when the same input is applied multiple times. A gauge with good repeatability will have a small variation in its output when the same input is applied multiple times.
• Stability: Stability refers to the ability of a digital gauge to maintain its accuracy over time. A stable gauge will have a small change in its output over time.

The accuracy of a digital gauge is important because it determines how well it can measure the physical property being measured. A gauge with high accuracy will be able to measure the physical property with a small degree of error. This is important in applications where accurate measurements are critical, such as in medical or scientific applications.
