Cable installation
The following points must be taken into account:
•
The cable should be installed in a conduit or should be securely fixed, given that
movements of the cable can induce reading errors.
•
The cable should be placed as far as possible from sources of electrical noise such as
switching gear and electrical machines.
•
The maximum length of the connection cable depends on the fluid conductivity. For
liquids with a conductivity higher than 500 μS/cm cable length can be up to 150 m.
3.3
Cable connection to sensor
For the sensor connection, first loosen the cable gland to allow the cable to slide in it.
•
Make sure that the two fixing screws of the cover do not protrude inside the cover (this
avoids damaging the O-ring of the sensor neck).
•
Apply a few vaseline on the sensor neck to aid inserting in the cover, specially on the O-
rings.
•
Connect the two cable connectors in their corresponding male connectors on the sensor,
mating the bumps in the guide of the male connectors.
