Basic Principle for the Mounting
NOTE!
The magnetic tape itself is not designed to withstand excessive mechanical wear. It is there-
fore important to ensure that the system is installed such that the mechanical contact between
tape and sensor head is mainly between the steel tape and the polymer sensor guide. These
two materials have been specifically paired for this application.
Avoiding contact between the magnetic side and the sensor could be achieved with a perfectly perpendicular
installation of the band. Yet, in reality this is not practicable. It is therefore preferable to install the tape with a
horizontal offset from the sensor. During operation this method will result in a forced contact between the steel
side of the band and the polymer guide of the sensor which guarantees an optimal operation of the system
.
