To extend the tubes of the sensor, use a collet coupling and an extra piece of
tubes.
The yellow nuts go into the inner
tubes
The collet nuts (the gold-yellow ones shown on the Fig. 10) connect the parts of
the inner tube. Once inserted into the parts of the inner tubes and screwed onto the
stud bolt, they don't have to touch but try to drive them as close to each other as
possible without breaking the tubes.
The outer coupling cylinder and its nuts must be tightened up as hard as
possible. The outer tubes of the sensor must touch each other.
