6.3.2 Shortening of the coaxial pipe
The coaxial pipe and the probe must be of the same length:
Fig. 6-1
► 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 and attach it
using the fixing bracket (B) at the
lower hole (C)�
A
B
C
L
K
= length of the coaxial pipe
L = length of the probe from the lower
edge of the process connection
(→ 6.3.1)
6.3.3 Determination of the probe length L if the coaxial probe is mounted
Only relevant if the probe length L (→ 6.3.1) is unknown:
► Measure the exact total length L
K
of the coaxial pipe (→ Fig. 6-1, on the right).
► Deduct 9 mm from the total length of the coaxial pipe: L
K
– 9 mm = L�
► Note down L� It must be entered during parameter setting of the unit (→ 10.2) �
