Construction

Electrical connection: The connection is accomplished
by means of a connection terminal (see Type code on
page 23).
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 (ISO 4762, M6 × 16 - A2-70) 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.
