Shrinkage Drain for Mortar and Concrete

The Shrinkage Drain: a 1-meter-long, U-shaped stainless steel profile designed to hold specimens. To minimize wall friction, the drain is covered with a removable Neoprene® sheet. One end of the Shrinkage Drain has a fixed, removable anchor, while the other end has a movable anchor that slides on three wheels. This anchor's movement is tracked by a highly sensitive digital probe. The digital probe is connected to Probe Interface Electronics, which converts the analog signals from the probe into a digital format.

Up to 10 probes can be connected via a digital bus system, allowing for distances of several hundred meters between the probes and the data logger. The system's data logger records data from multiple shrinkage drains and stores it as standard ASCII text files. Optional synchronous registration of temperature and humidity is available, with several temperature channels and a mixed temperature/humidity channel. A balance can also be connected as an option.

The data logger includes an Ethernet network interface, enabling easy integration into a local intranet. Data can be read and visualized using any standard web browser, such as Firefox or Internet Explorer. For further data analysis, programs like Microsoft Excel® or any similar visualization software are recommended.

Standards

No special PC software is required; you only need your web browser. The Shrinkage Drain is now described in the Austrian standard OENORM B 3329:2009-06-01 for grout requirements and test methods."
