The Schleibinger viskomat XL, Rheometer for Mortar and Fresh Concrete up to 8 mm Grain Size Based on 20 years experience with rheometers for mortar and fresh concrete, Schleibinger has developed a new instrument called viskomat XL. Its filling the gap between the viskomat NT for mortar and paste with a specimen volume of 360 ml and the concrete rheometer BT2 with a sample volume of 20l. The operation principle of the viskomat XL is near the same as for the viskomat NT. So a mixer formed probe is measuring the torque,and the specimen vessel is rotating. An additional scraper is cleaning the wall of the vessel.
Very dynamic speed range The speed may be 0.001 to 100 rpm in both directions, clockwise or counter clockwise. You may be define the speed in several steps, in an linear increase or decrease of speed. As option also an oscillating or a logarithmic mode is possible.
High Torque Range The viskomat XL has a torque range from0..500 Ncm with a resolution of 0.05 Ncm and accuracy better then 0.2 Ncm. Optional we can install a sensor with a torque range up to 1000 Ncm and a accuracy of 0.8 Ncm
Temperature control Temperature control is realized by a double wall specimen container, where a cooling liquid is circulating. The specimen temperature is measured with a RTD mounted inside the shaft of the probe.
High Time Resolution The sampling rate my be set from 0.005s .. 1min. Shear Stress Control Mode As option you may run the viskomat XL with a shear stress controlled mode. So you preset the torque over time, and the speed is automaticly controlled to achieve the predefined torque
Software The viskomat XL is controlled with a built in computer or via a network interface. TFT- screen, keyboard and mouse included. If you prefer a network connection simple connect your PC and start your Internet Explorer for full control and data transfer. No special software installation necessary.
