How does SWIR material detection work?

SWIR sensors analyze the reflected light from organic materials, enabling precise differentiation of paper, wood, plastics and other materials in real time.

In which industries is polyIdent used?

polyIdent is used in various industries, including the paper industry, wood processing, food production, plastics processing and mechanical engineering.

Up to what temperatures do optoGuard sensors operate?

optoGuard models are designed for extremely hot industrial environments and, depending on the model, also support ATEX zones.

How does inline humidity measurement save energy?

Real-time control of dryers prevents over- and under-drying, which significantly reduces the energy required in the drying process.

SensoWeb "Guard" - Break-away detectors for dryer groups, presses, etc.

SensoWeb "Guard" - demolition detectors

Our tear sensors were developed specifically for the harsh environmental conditions in the paper machine and have been further optimized over many years:

Thanks to the fiber optic concept, the sensors can be placed in less exposed areas, High performance sensors enable high pollution reserves robust fiber optic optics minimize transmission losses and are also optimally protected against mechanical stress!

This also enables them to high temperatures, humidity, pollution etc. long term Reliable tear detection in around 200 paper and cardboard machines worldwide!

Another highlight is our globally unique material-sensitive Tear detectors that enable reliable tear detection even against the screen background, despite high humidity and temperature.

On the following pages, familiarize yourself with the different models, each of which has been optimized for different areas of application:
