Construction
Electrical connection:
The electrical connection is made
via a cable or a connector (see Type code breakdown on
page 21).
BTL housing:
Aluminum housing containing the
processing electronics.
Mounting thread:
We recommend assembling the
transducer on the fastening screw thread:
– BTL7-…-TB: M18×1.5
– BTL7-…-TZ: 3/4"-16UNF
– BTL7-…-TT: M30×1.5
The transducer has an additional thread at the end of the

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 21 mm: Nominal length from 25 mm to 3250 mm
Damping zone:
Area at the end of the rod that cannot be
used for measurements, but which may be passed over.
