Multimode tribometer FT3

Multimode tribometer FT3 is intended for studying of material friction and wear characteristics as well as lubricant characteristics. The device is equipped with changeable actuator heads realizing one of two optional testing schemes: rotation of tree indentor against stationary disk or reciprocal motion of the indentor against flat sample. Implementation of testig schemes with stationary flat sample enables testing of lubricants wihout limitations and use of special techniques. The lower cell design admits installation of a flat sample and also provides for its temperature control (using extra aplliances). The tribometer is powered by a servo drive allowing speed control in wide range. The friction pair loading is realized by dead weights through a lever. The instrument during the tests measures and records friction force (friction moment), linear wear of the friction pair, load on the friction pair and temperature.

Change of the testing scheme is carried out by replacement of actuator head while friction force is measured with the single gauge cell of original design. As moving samples (indentors), balls (diam.3—6 mm) or pins (diam. 6.5 mm) can be employed.

Panel of tribometer control software

The tribometer software pack is intended for data acquisition at host PC with a Win32 OS (Windows XP SP2 and higher).

The program allows to acquire the digital data from the tribometer signal ADC unit and store them in a text format. Further processing? analysis and visualization may be carried in third part programs (e.g., SurfaceХplorer or Microsoft Excel).

Minimal configuration of host PC (not included in the delivery set): Celeron® 1.7 GHz, RAM 512 MB, HDD 160 GB, VRAM 64 MB, monitor 17" 1024x768x32 bit, MS Windows® XP SP2, USB port.
