Sensorik Austria offers customers in paper industry special sensor systems for moisture measurement, which are based on the proven multi-channel technology and can be used even under harsh environmental conditions:
- Thanks to the fibre optic setup, sensors can be used practically at any position in and outside the dryer section
- Heavy duty fibreoptic cables with lengths of up to 15 m enable the sensor electronics to be positioned in less exposed places
- Special sensor heads with integrated air flushing successfully handle high levels of pollution
- Newly developed holders facilitate positioning and alignment of the cantilever with the sensor head
- The fibre-optic concept also permits the placement of several sensors across the width of the paper web or traversing across the paper web!
