7.5.2 Determine probe length L for single probes
►
Precisely measure the probe length L. The reference point is the lower edge of
the process connection (Fig. 7-8).
►
Note the value. It is needed for setting the device parameters
.
7.5.3 Shortening of the coaxial pipe
The coaxial pipe and the probe must be of the same 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).
