Shrinkage-Cone deltaEL
A Laserbeam Measures the very early Shrinkage and Expansion of Building Materials. Touchless and with 1 Mikron Resolution
With Schleibingers latest innovation the Schleibinger Shrinkage Cone deltaEL it is possible to measure the
shrinkage or expansion of fluid building materials in the first minutes and hours after start of mixing. The
expansion of the building material is registered touchless and very exact by a laser beam. There is no
mechanical coupling between the fluid and the sensor necessary.
To ensure that the measured distance correlates with the relative length change of the material we use a
cone formed specimem container.
The length change is registered with a resolution of 1/10 mikron. The measurement values are digitised
and stored by the software delivered with the system. Synchronous with the length change, temperature,
rel. humidity, ore data from the Schleibinger Schwindrinne may be stored by the software.
How it works:
- Fill the fluid building material into the cone formed specimem container
- The container is set under the laser unit , which is mounted on a high performance boom stand.
- With a rack and pinion the distance is preset to about . 0 µm .
- The automatic offset adjust is done by a mouse click on your PC .
- An autonomous data logger will register your data for several weeks on an integrated CF-card memory
- The data-logger has a network interface. You can easily readout the data, with any browser software like Internet-Explorer ore Firefox. No speciall PC software required!
