SensorÜbertragungskennlinien

SensorÜbertragungskennlinien, which translates to "sensor transmission characteristics" or "sensor transfer function," describes the relationship between the input signal of a sensor and its corresponding output signal. This characteristic is crucial for understanding how accurately and reliably a sensor converts a physical phenomenon into a measurable electrical signal.

The transmission characteristic is often represented graphically as a curve, plotting the output signal on the vertical axis and the input signal on the horizontal axis. Ideally, this curve would be a straight line, indicating a linear relationship where the output changes proportionally to the input. However, real-world sensors rarely exhibit perfect linearity.

Deviations from linearity can manifest in various ways, such as saturation at high input levels, hysteresis (where the output depends on the direction of change of the input), or non-uniform sensitivity across the input range. These non-linearities can introduce errors in measurements if not accounted for.

Understanding the sensorÜbertragungskennlinie allows for proper sensor selection for a given application, calibration procedures, and the development of compensation algorithms to improve measurement accuracy. It is a fundamental concept in sensor technology and data acquisition. The specific shape of the transmission characteristic is determined by the sensor's operating principle and its physical design.
