Brightness Sensor

For pulp and paper applications

Key Features

Wide, dynamic measuring range with fast update rate
Single sided, reflective measurement
Brightness according to TAPPI T452
Real-time window into the stock preparation process

Measuring Method

The Scienta LED based sensor model 7280 measures Pulp and Paper sheet Brightness in BU units online using a multidirectional receiver setup enabling a fiber orientation independent measuring of the scattered light modelled after the TAPPI T452 standard. The LED light source has an extremely long life and thus makes the sensor practically maintenance free. The measurement update frequency is 5 Hz making it well suited for a single point installation.
