3. INSTALLATION OF THE TRIAXIAL EXTENSION CABLE
3.1 Preliminary considerations
•
The cable type to be used is determined by the sensor type. It is very important that you use the triaxial
extension cable sent with the sensor.
Warning - Danger Caution
Never install triaxial extension cables on high voltage components.
Caution
•
Installation of the triaxial extension cable usually follows that of the sensor.
•
Before installing the triaxial extension cable, it is important to determine where the enclosure (containing
one or two modules) will be installed, keeping in mind the length of the triaxial extension cable. The cable
must be protected by a combination of conduit, protective tubing, and heat-shrinkable tubing.
•
Triaxial extension cables are terminated with an SMA plug (male contact) connector on the signal condi-
tioning module end, and an SMA jack (female contact) connector on the sensor end.
Cable clamps must be used to secure all
components subjected to vibrations. This step
of the installation is essential to prevent
damage from wear by abrasion.
Use clamps to secure the protective tubing
and elbow assembly to the top of the stator.
Refer to
Figure 7 : “Preparing holes for the
cable clamps” .
Figure 5 : Securing the protective tubing and coupling
Triaxial extension cables are calibrated and must never be cut or altered.
The ground lugs must be electrically connected on BOTH ends of the triaxial extension
cable. On the sensor side, the ground lug must be connected to the stator frame. On the
signal conditioning module end, the ground lug must be connected to the module ground
screw.
