3.1

Construction

Electrical connection: The electrical connection is made
via a connector (see Type code breakdown on page 14).
Housing: Aluminum housing containing the waveguide
and 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 starting on
page 12).
Nominal length: To optimally adapt the transducer to the
application, nominal lengths from 50 mm to 4572 mm are
available.
3.2

Function

The BTL6 transducer contains the waveguide which is
protected by an aluminum housing. A magnet is moved
along the waveguide. This magnet is connected to the
system part whose position is to be determined.
The magnet defines the position to be measured on the
waveguide.
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 speed.

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 conver-
ted by a coil into an electrical signal. The travel time of the
wave is used to calculate the position.
This information is transferred via the VARAN interface.
VARAN is an industrial bus system based on the physical
layer of the Ethernet (see www.varan-bus.net).
