2.3. Sensor head installation
The fiber-optics cable is delivered mounted to the sensor head. Feed the free fiber-optic cable through
the flexible conduit. This is easiest, if the conduit is laying straight on the floor and the fiber-optic
cable is at room temperature. Connect the conduit to the sensor head. If you pull, pull the fiber-optic
cable from the outer jacket, not from the connectors. The maximum force for pulling from 2 cables
is 50 Newton (11 lbf). The minimum bending radius is 50 mm (2"). The sensor should be installed
about 25 cm (10") inside from the edge of the web and 15 cm (6") above it. Standard range is 10 -
30 cm (4 - 12").
Fig. 2.2. Typical installation.
Install the mounting clamps or the rack (optional) on paper machine’s frame or other solid mounting
structure. Leave 20 - 30 cm (8 - 12") between the clamps. It is recommended to leave option to adjust
clamp height so that sensor head can be positioned optimally during the start-up.
