Measuring system and process for determining properties of a running fibrous material web in a drying section of a machine producing the fibrous material web. The system includes at least one upper roll and at least one lower roll. The fibrous material web is arranged to partially wrap the at least one upper roll and the at least one lower roll and to run between these rolls at an angle between about 0° and 45° to a vertical. A sensor guide is arranged crosswise to a web run direction, and at least one sensor is arranged to traverse the sensor guide in the web run direction in a region of the at least one lower roll. The sensor is structured and arranged for determining a web parameter, and is oriented to form a maximum angle of about 60° to a horizontal through an axis of the lower roll.
