Abstract

Disclosed is a sensor arrangement on a process installation comprising at least two sensor tiles, wherein each sensor tile comprises a support and a plurality of sensors arranged on the support for determining a physical or chemical variable of a measuring medium, a process characteristic of the measuring medium, and/or a state of the process installation. A first sensor tile comprises a control unit having a transmit and receive module for data exchange with a control unit of a second sensor tile. The first control unit of the first sensor tile and/or a second control unit allocated to the sensor arrangement is designed to weight the values determined by each sensor tile. Weighting may be a function of the measured value variations of the sensor tile, the position of the sensor tile in the process installation, and/or the function of the sensor tile.
