Product description (continued)
4.2
Function
To determine the position of a plant component, a position
magnet is connected to the component. Together they are
moved along a waveguide located inside the BTL.
An internally generated INIT pulse interacts with the
magnetic field of the position magnet to generate a
torsional wave in the waveguide which propagates at
ultrasonic velocity. The component of the torsional wave
which arrives at the end of the waveguide is absorbed in
the damping zone to prevent reflection. The component of
the torsional wave which arrives at the beginning of the
waveguide is converted by a coil into an electrical signal.
The position of the magnet and thus at the same time that
of the plant component is determined from the running
time of the shaft.
Depending on the version, 1 or 2 outputs are available and
the position is output as a voltage or current value with
rising or falling gradient.
Up to 2 magnets can be used for FMM (Flexible Magnet
Mode).
The following functions can be selected for the output
values:
–
Position
–
Velocity
–
Position difference
The entire range of functions can only be
configured with the PC software B
E
T
(BET). For this, the IO-Link
nginEEring
ool
master must be connected. Communication is
realized via IO-Link.
