Construction

Electrical connection: The electrical connection is made
via a connector (see Type code breakdown on page 20).
BTL 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 on page 17).
Nominal length: To optimally adapt the transducer to the
application, the following nominal lengths are available:
Nominal length
50 to 4572 mm
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
converted by a coil into an electrical signal. The travel time
of the wave is used to calculate the position. The
measuring value is output as a 32-bit value with a sign
relative to the null point.
