Multimode tribometer FT2

Multimode tribometer FT2 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 design of lower cell for flat sample also provides for its temperature control. The tribometer is powered by a servo drive allowing the actuatr speed control in wide range. The friction pair is loaded by the automated sytem driven by a stepper motor. The instrument allows to measure and record friction force (friction moment), linear wear of the friction pair, load on the friction pair and temperature athe the testing.

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—4.5 mm) or pins (diam. 6.5 mm) can be employed.

On the front panel of the tribometer are placed alphanumerical LCD (displaying current measured parameters and other critical information about the operation mode) and function buttons for quick control over the device without the host PC.
