2.5.2 Installation of VITO Interface in close proximity of VITO probe / MRT
In some cases there is not sufficient space to install the VITO interface on top of the VITO
probe / MRT.
In these cases a (preferable flexible) metal conduit is advised, although also a set of
matching coupling and unions can be considered.
Please contact the factory for detailed advice.
2.5.3 Installation of VITO MPT probe in combination with SmartRadar FlexLine
The 361 VITO MPT temperature probes with six (6) or less elements can be directly
connected to a 990 SmartRadar FlexLine. In this case the FlexLine radar must be
equipped with a FII-RTD board and the 762 VITO Interface and SmartRadar FlexLine
FII-VT board are not required.
For this type of installation the maximum distance between the FlexLine radar and the
VITO MPT probe is 600 cm (236 inch). The VITO MPT probe should be ordered with the
correct extended flying leads, i.e. 250 cm (98 inch) or 600 cm (236 inch).
Note:
Although it is not advised, the wires can be extended beyond the above specified
600 cm. In this case an extra junction box (JB) is required, and preferably the same
wire should be used. Please contact the factory for detailed advice.
For protection and shielding of the temperature sensor wiring between VITO MPT probe
and SmartRadar FlexLine, it is strongly advised to use preferably flexible, metal conduit.
The conduit should be properly bonded to the temperature sensor on one side and the
SmartRadar FlexLine on the other side.
Both connections should be properly sealed and protected against water ingress, with for
example PTFE
®
tape and self vulcanizing electrical tape on the outside.
For the connection of the VITO MPT probe wiring to the 990 SmartRadar FlexLine, refer to
the installation guide SmartRadar FlexLine.
