Construction
Electrical connection:
The connection is accomplished
by means of a connection terminal (see Type code on
page 30).
Housing:
A heavy-duty stainless steel housing with a
modified 1/2"-14 NPT threaded conduit opening for cable
entry (conduit is not included in the scope of delivery).
Modified conduit entry in accordance with FM Standard
3615, Chapter 3.3.3, Paragraph D, Section 1.
The internal electronics module can be replaced without
removing the pressure housing.
Fastening:
For secure fastening, tighten the BTL with
cylinder screws (M6 × 45 - A4-70) at all 6 mounting holes
(see Fig. 3-1). All screws must be tightened with 3.5 Nm.
The BTLs 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 starting on
page 28).
Nominal length:
Defines the available measuring range.
Rods with various nominal lengths from 25 mm to
7620 mm are available depending on the BTL version.
Damping zone:
Area at the end of the rod that cannot be
used for measurements, but which may be passed over.
