3.1 Construction
Electrical connection: The electrical connection is made
via a cable or a connector (see Type code breakdown on
page 27).
Housing: Aluminum housing containing the processing
electronics.
Mounting thread: We recommend assembling these
transducers on the mounting thread:
– BTL7-...-A/B: M18×1.5
– BTL7-...-Y/Z: 3/4"-16UNF
– BTL7-...-CD: M22×1.5
The transducers with Ø 10.2 mm and 12.7 mm have an
additional thread at the end of the rod to support larger
nominal lengths.
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).

– Ø 8 mm: Nominal length from 25 mm to 1016 mm
– Ø 12.7 mm: Nominal length from 25 mm to 2000 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.
