What is meant by the term "repeatability" in sensor performance?

In sensor performance, “repeatability” refers to the ability of a sensor to produce consistent output readings when the same input is applied repeatedly under the same conditions. In other words, repeatability measures the sensor’s ability to provide the same result when the same measurement is taken multiple times. It is an indication of the sensor’s precision and reliability in producing consistent measurements. Repeatability is typically expressed as the maximum difference between repeated measurements, often stated as a percentage of the full-scale range or as a fixed value. A sensor with high repeatability will consistently produce output readings close to each other when measuring the same input, while a sensor with poor repeatability may yield significantly different readings for the same input under identical conditions.
