Shrinkage-Drain

Now described in the Austrian standard:
OENORM B 3329:2009-06-01
Grout - Requirements and test methods

The Shrinkage Drain is made of a 1m long u-shaped stainless steel profile which contains the specimen.. To avoid wall friction the drain is covered with a removable Neopren ® sheet. On one side a removable anchor is fixed. On the other side this anchor is movable and sliding on three wheels. The motion of this anchor is registered by a high sensitive digital probe .

 

As displacement sensor we are using a digital probe which is connected to the Probe Interface Electronics  which converts the analogue signals from the probe head into a digital format.

Up to 10 probes may be connected over a digital bus system. The distance between the probes and the Datalogger may be several hundreds of meters. A data-logger supplied with the system the data of several shrinkage drains are registered and stored in the logger as standard ASCII text files. Optional a synchronous registration of temperature and humidity is possible. Several temperature channels and a mixed temperature /humidity channel are available.You may also connect a balance (option).

The logger has a network interface (Ethernet) So you can easily integrate it into local Intranet. With a standard web-browser software you can readout the data, and visualize it. For further data handling we recommend Microsoft Excel ® ore any similar visualization program.

No special PC software is necessary. You need only your browser-software like Firefox ore Internet-Explorer.
