KAPAZITIV ARBEITENDE SENSOREINHEIT ZUR ÜBERWACHUNG DER QUALITÄT VON FASERMATERIAL UND DAMIT AUSGERÜSTETE MASCHINE ZUR HERSTELLUNG VON MASCHENWARE
摘要:
A capacitively operating sensor unit for monitoring the quality of fiber material (1) is described. The sensor unit comprises a measuring electrode (18) extending in the transport direction (x) of the fiber material (1), a transmitting electrode (21) disposed opposite of the measuring electrode (18) at a distance thereto, and a shield electrode (19). An alternating current generator is connected between the transmitting electrode (21) and the shield electrode (19), while the measuring electrode (18) is connected to an evaluation electronics system. According to the invention, the transmitting electrode (21) is provided with a projection (26) protruding in a raised manner in the direction of a sliding surface of the measuring electrode (18).
