Strip edge position detection for metal strips

Using the inductive edge sensor, the edge position of metal strips is detected in a contact-free manner. In combination with a control amplifier and an actuator, a strip edge guiding system is implemented. Using two edge sensors, a strip centre guiding system is provided.

The inductive edge sensor provides, in combination with the separate BMI2.02 evaluation electronics, an output signal UA which constantly changes according to the strip position of metal strip. The inductive edge sensor basically consists of transmitting and receiving coils, which are accommodated in a protective enclosure and wired to the preamplifiers (PIB04.0x).

A maximum of 2 edge sensors may be simultaneously connected to the BMI2.02 evaluation electronics whereby an output voltage and the difference between the two output voltages is available for each edge sensor.
