AquaSonde Vent/Data Hub is a termination hub that allows a vented cable and desiccant bottle to be attached. Allowing the sensors vent tube to be protect from moisture build up and provides access to the data collected from a Leveline or Aquaread sensor. It can also be used to allow for the connection to a QuickDeploy Key for checking the condition of the loggers battery and memory condition. The Hubs are also available with 5, 10, 20 or 30m vented extension cables.
The AquaSonde Vent/Data Hub can be used for fitting a desiccant cartridge to the Vented Leveline Cables. This can also be used where you are connecting to an external logger.You can connect the sensor and desiccant to a Vent/Data Hub to allow the desiccant to be fitted to the vent tube of the sensor, whilst a separate connector can be used to connect to the logger. This can also be used with the QuickDeploy Key during installation, or checking battery and memory status of connected loggers.
The desiccant used within the Aquaread Desiccant Cartridges is a non-toxic, self-indicating synthetic amorphous silica designed to change colour as it absorbs moisture from orange to clear. Desiccant Cartridges are available in two sizes.
The choice of small (DC-50) or large (DC-100) Desiccant Cartridge is dependent upon the humidity at the deployment site and the expected maintenance frequency. If the deployment site is humid or the time between maintenance visits is expected to be long, the large (DC-100) Desiccant Cartridge is recommended. The DC-100 can also be split between two DC-50 bottles, if you want to replace older desiccant.
The time taken for a fresh, dry Desiccant Cartridge to go from orange to clear (i.e. become fully saturated) is dependent upon site conditions. Regular maintenance checks should be made on the installation and the Desiccant Cartridge should be replaced or regenerated before it is completely saturated (clear).
When the desiccant in a Desiccant Cartridge has absorbed all the moisture it can and has changed from orange to clear, it can be regenerated and reused by a simple drying process.
Spread the desiccant crystals evenly on a suitable baking sheet and bake in an oven between 100°C and 200°C for around an hour or until the colour has changed from clear back to deep orange. After being allowed to cool, the crystals can be replaced in the Desiccant Cartridge and reused.
