Dimensions, design and function
4.1
Construction
Electrical connection: The electrical connection is made
via a connector (see Type code on page 16).
Housing: Housing containing the processing electronics.
Magnet: Defines the position to be measured on the
waveguide. Magnets are available in various models and
must be ordered separately (see Accessories on
page 15).
Measuring length: Defines the travel/length range
available. Sensors with measuring lengths from 25 mm to
4000 mm are available.

Function
To determine the position of a plant component, a 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 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, the position is output as a
voltage or current value with rising or falling gradient.
