Mortar, Cement and Fresh Concrete (8mm grain size) Rheometer, Viskomat XL
The Viskomat XL is filling the gap between the Viskomat NT for mortar and paste with a specimen volume of 360 ml and the con¬crete rheometer BT2 with a sam¬ple vol¬ume of 20l. The operation principle of the viskomat XL is similar to that of 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 180 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 from 0..300Ncm with a resolution of 0.05Ncm and accuracy better then 0.2Ncm. Optional we can install a sensor with a torque range up to 1000Ncm and an accuracy of 0.8Ncm
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 .. 10min.
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 automatically controlled to achieve the predefined torque.
The Viskomat XL is controlled via a network interface . Simple connect your PC and start your Internet Explorer for full control and data transfer. No special software installation necessary.
