Shrinkage-Drain

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.

Temperature controlled option for the Shrinkage Drain
For the Shrinkage drains with the size of 1000x100x60 mm and 1000x60x40 mm.
The bottom and walls of the drain are prepared to connect an apropriate cooling and heating unit for temperature control of the specimen. Each drain has an input and output connection. Several drains may be connected in series.

Datalogger SR for the Shrinkage Drain
to record measurement data from the Schleibinger Shrinkage Drain. Up to 10 Schleibinger Shrinkage Drains can be connected to the data logger. With the data logger the Shrinkage Drain is fully networkable. The Shrinkage Drain can thus be integrated into an intranet and thus allow access to the measured data at any time. For the displaying of the data a web browser such as MS Internet Explorer, Firefox, Chrome, Opera etc. is needed. The measurement data is recorded nonvolatilely on an internal memory for up to four weeks. For the operation no extra computer is needed. The data can be retrieved numericaly or graphically from any workstation in the network and exported as Excel file or bitmap file. No additional software is needed.
Hardware requirements: computer or network with Ethernet interface 100BaseT, web browser, TCP/IP protocoll, fixed IP address.
Delivery: Interface electronics incl. Software and data logger for up to 10 Shrinkage Drains, carrier plate for multiple connectors, user manual.
Dimensions: 24 x 21 x 6 cm
Weight: 1.8 kg.

Combined Temperature and Humidity Channel
Combined temperature and humidity sensor for the measurement of enviromental conditions.
For each data logger one combined sensor and one thermocouple (temperature sensor, Type K) can be integrated.

• measuring range humidity sensor: 0...100 % ± 1.8 % r.h. not condensing,
• temperature accuracy: ± 0.5 °C.
  

Delivery: factory installation of the interface, combined temperature and humidity sensor.

Channel for the Thermocouple
Temperature channel with thermocouple type K (Ni / CrNi), which is installed in the electronics of the basic equipment. Up to 3 temperature channels are possible per datalogger. Delivery: factory installed interface, thermocouple type K.
