sensorfunksjon

Sensorfunksjon, often translated as sensor function, refers to the characteristic behavior of a sensor in response to changes in a physical quantity. It describes how a sensor's output signal, which can be electrical, optical, or another form, varies as a function of the input stimulus. This relationship is fundamental to understanding and utilizing any sensor effectively.

A sensor's function is typically defined by its transfer characteristics, often represented graphically. Key aspects of sensor function include sensitivity, which quantifies how much the output changes for a given change in input. Linearity describes how proportional the output is to the input over a specific range. The operating range, the set of input values for which the sensor provides a reliable and accurate output, is also a critical part of its function.

Other important considerations within sensor function include resolution, the smallest change in input that the sensor can detect, and accuracy, how close the measured value is to the true value. Response time, the speed at which a sensor reacts to a change in input, and hysteresis, the difference in output for the same input when approached from different directions, are also key aspects that define a sensor's behavior. Understanding these elements of sensor function is crucial for selecting the right sensor for a particular application and for interpreting the data it provides.
