5. Check that O-ring 90x3 is in the sensor body
sealing groove.
6. Place the base plate close to the installation posi-
tion with the current cable aligned in the same
position as the probe antenna.
7. Push the thermoelement cable through the middle
hole in the base plate. Place the base plate about
10 mm away from the sensor body and at the
same time check that the microwave cable connect-
ors on the base plate side are lined up with their
feed-through holes.
8. Put an M6x50 screw temporarily in the uppermost
mounting hole so that the base plate will stay in
place while the microwave cables are being
mounted.
9. Use pointed pliers to take hold of the body of the
microwave cable connector that is on the base
plate side. Push the threaded part of the connector
far enough into the hole in the base plate so that
the cable's clamping bush and O-ring start turning
in the thread.
10. Hold the connector body in place with an 8mm set
wrench and use a 10 mm box key attached to the
Belzer Torque driver to tighten the clamping bush
of the antenna cable from the opposite side of the
base plate to 1 Nm torque. Repeat the same steps
for the other connector.
11. Push the base plate all the way against the sealing.
Apply locking medium Loctite 270 to the threads
of the base plate's five free mounting holes and
put M6 lock washers and M6x20 Allen screws into
the threads.
12. Tighten the screws to 8 Nm torque.
13. Place the thermoelement cable into the groove in
the base plate and tape it into place with thin tape.
14. Install the sensor electronics as described in
Chapter 11.1.
