of ice are most likely to occur first. Mount the sensor within the area to
be monitored and heated.
Arrange the sensor in such a way that the draining melt water runs onto
the sensor's measuring surface. This ensures that moisture is detected
as long as there is any. It is important that the sensor surface lies
horizontally and is level with the surrounding surface material.
The sensor can be mounted in a ground sleeve E650C-G-HOUSING.
E650C-G-HOUSING is included in the package of E650C-G sensor
but also available as a separate spare part accessory to be ordered
separately. E650C-G-HOUSING contains both the metal sleeve (housing
part) and the lid to close the housing during installation. When the open
area is built, this ground sleeve is placed into the surface without the
sensor in such a way that there will be an even surface after installation
of the sensor.
Especially in case of surfaces which need a high processing temperature,
such as poured asphalt (>75°C), the fitting of a ground sleeve should be
well provided for. In order to avoid that the ground sleeve sinks into a soft
surface later (e.g. in a sand bed for stone paving), it is recommended to
create a firm foundation for the sleeve (e.g. by putting a concrete support
underneath).
A protective conduit needs to be used for the sensor cable. This is
beneficial both during a new installation and in case of a replacement.
Depending on the weight and material of the surface either a plastic
conduit or a steel pipe DN20 can be used. Make sure that the openings
of the empty conduit and the ground socket are securely closed during
the construction works.
To make sure that the ice and snow detection system works properly,
take care that the sensor is surrounded by heating cable and that the
minimum heating time is long enough so that melt water can moisten
the sensor.
Installation of the housing and the sensor in the ground - fig. D0
When choosing a suitable place to place the housing and sensor in the
ground, take into account the instructions above. First place the housing
in the ground (along with the protective pipe leading to the controller,
the protective pipe is not included) and cover the top of the housing with
the cover. If the cover seems too loose, you can use gaffer tape to affix
the cover to the housing. The protective tube should be 20 mm or less
in diameter, the remaining space between the protective tube and the
hole in the housing should be covered with silicone or adhesive or gaffer
tape. When the surrounding area is ready, remove the cover and place the
sensor in the housing, securing it with 3 screws (included). The sensor
cable should go through the protective tube and should be connected to
the controller at the other end.
Installation in horizontal flat open areas - fig. D1
The sensor needs to be installed inside the area to be monitored and
heated in such a way that the sensor surface is level with the surrounding
surface and the sensor surface remains free. The sensor must not stick
out of the open area but can rather be a few mm lower so that melting
water is collected.
Installation in open areas with a slope - fig. D2
In case of a slope, make sure that the sensor surface lies horizontally in
order to be able to collect snow or melt water.
If the sensor surface does not lie horizontally, this may lead to errors in
detecting moisture.
