Fitting instructions
Requirements for the location
The DCX logger unit is installed in a stable position at the measurement location
in order to record a groundwater level.
• If the logger is fully sunk into the ground (e.g. in a sewer shaft), free movement of
the water level in the tube must be ensured by above-ground openings (ventila-
tion apertures)
• Lateral movements of the level sensor may cause measuring errors or cable
breaks. For these reasons, fit the level sensor in a calm zone or in a suitable
protective tube
• On VG versions, the sensor cable contains a capillary tube to compensate for
atmospheric pressure. Therefore, position the cable end of VG versions in a dry
area or use moisture absorber cartridges
Installation in level tubes
Place the cap lock in position and screw the two grub screws in to prevent it from
turning (anti-theft protection)
→
requires a slotted screwdriver, size 2 (not included in the scope of delivery)
Guide the sensor with the sensor cable into the level tube by hand. The sensor
cable must be free and extended as it hangs in the level tube; it must not change
its position as this would falsify the measurement results.
→
For system lengths of more than 50 m, cable strain relief is recommended,
e.g. using a straining clamp (see Accessories)
Screw the matching adapter ring onto the read-out unit. After installation, the
adapter ring will lie on the edge of the level cap lock. Secure the logger unit in the
adapter ring using the circlip supplied with the product.
