Chapter 2 – Introduction
Note
In case the magnetic sensor is used for other purposes than specified above or is modified
all warranties against the Götting KG are null and void.
The magnet sensor is only used according to section 2.1 on page 7. The magnet sensor is
only mounted, configured, commissioned, operated, maintained and dismounted by per-
sonnel according to section 2.2 on page 7.
2.4 Functional Principle
The sensor is based on digital magnetometer technology for the detection of the magnetic
field above the magnetic tape.
Figure 1
Detection of the magnetic field
The sensor has three independent detection systems. Via two digital inputs one of two
tracks can be chosen dynamically. Thus the sensor can detect junctions and follow turnoffs
(also see 5.3 on page 21).
