Prozesswert

Prozesswert is a term used in process engineering, manufacturing, and related fields to denote the current numeric value that describes the state of a process parameter at a given moment. The Prozesswert can be obtained directly from measurements (for example from sensors), calculated from data (such as a moving average), or derived from a combination of sources, and is typically associated with a timestamp and unit of measurement. It serves as a concrete representation of how a process is performing at a specific point in time.

In practice, Prozesswerts are used for monitoring, control, and analysis. They are often compared with a reference or target value (Sollwert) and may be evaluated against tolerance bands to determine whether the process is within acceptable limits. In control systems, the Prozesswert acts as feedback that informs actuators and regulators to maintain or adjust process conditions. In analytics, sequences of Prozesswerte form time series that support trend analysis, anomaly detection, and process capability assessments. Common examples include temperature, pressure, flow rate, cycle time, production yield, energy consumption, and defect rate. The interpretation and relevance of a Prozesswert depend on the specific process context, and data quality, measurement error, and time lag are important considerations for its reliability.
