7.5.3 Shortening of the coaxial pipe
The coaxial pipe and the rod must be of the same end length:
► Remove fastening bracket and
centring piece (A, B)�
► Shorten the coaxial pipe to the
requested length: L
K
= L + 9 mm
► After shortening, at least one hole
(C) for insertion of the fixing bracket
has to be left�
► Remove all burrs and sharp edges�
► Insert centring piece (A) at the
lower end of the pipe (for lengths
> 1400 mm use a second centring
piece in the middle of the pipe) and
attach it using the fixing bracket (B)
at the lower hole (C)�

K
= Length of the coaxial pipe
L = Length of the rod from the lower edge
of the process connection
(→ 7.5.1)
7.5.4 Determine rod length L for coaxial probes
► Measure the exact total length L
K
of the coaxial pipe (fig� 7-9, on the right)�
► Deduct 9 mm from the total length of the coaxial pipe: L
K
– 9 mm = L�
► Note down L� It is needed for setting the device parameters (→ 11.2)�
