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25).
Nominal length: Defines the available measuring range.
Rods with various nominal lengths from 25 mm to
7620mm are available depending on the version:
– Ø10.2mm: Nominal length from 25mm to 7620mm
– Ø8mm: Nominal length from 25mm to 1016mm
Damping zone: Area at the end of the rod that cannot be
used for measurements, but which may be passed over.
Calibration device: Additional device for calibrating the
transducer (not for BTL7-….-S140).

3.1 Construction
Electrical connection: The electrical connection is made
via a cable or a connector (see Ordering code on
page29).
BTL housing: Aluminum housing containing the
processing electronics.
Mounting thread: We recommend assembling this
transducer on the mounting thread:
– BTL7-…-A/B: M18×1.5
– BTL7-…-Y/Z: 3/4"-16UNF
The transducers with Ø10.2mm have an additional thread
at the end of the rod to support larger nominal lengths.
