ingångsspann

An ingångsspann, meaning "input span" or "measurement range," is a term used in instrumentation and engineering to define the range of input values a sensor or measuring device can accept or process. It specifies the lowest and highest values that the device is designed to accurately measure. For example, a temperature sensor with an ingångsspann of -20°C to +120°C can reliably measure temperatures within that specific range.

Understanding the ingångsspann is crucial for selecting the correct instrument for a given application. If the expected input values fall outside this range, the device may provide inaccurate readings, saturate (clip the signal), or even be damaged. The ingångsspann is often related to the device's output span, which represents the range of output signals produced by the device corresponding to the input span.

The ingångsspann is a fundamental specification that helps engineers and technicians ensure that their measurement systems are properly configured and will yield meaningful and reliable data. It is typically clearly stated in the device's technical documentation or datasheet.
