Web edge control - web edge monitoring in the high temperature area

Detecting the web edge of high-speed endless tapes such as a felt in a paper machine is no easy task:

• mechanical switches wear out and can also affect the web edge;
• horizontal oscillation often cannot be controlled with sufficient precision by means of a digital switch;
• sophisticated measuring systems cannot withstand high environmental stress caused by temperature, moisture and pollution.

• SensoWeb “Edge-analogue” with an analogue output signal
