The main differences between the four models of our Triboster TSf series

TSf-503

TSf-503

The TSf-503 is our most versatile and adaptable model to evaluate the static and kinetic coefficient of friction of all kinds of samples with different shapes.
Featuring seven measuring routines, a built-in temperature sensor, and a full set of six weights, the TSf-503 is widely used in research and development.

TSf-303

TSf-303

The TSf-303 is identical in design to the TSf-503, but only features the standard repetition measuring routine and a set of only two different weights.
The reasonable TSf-303 is the ideal model to perform reliable measurements for the routine quality assurance.

TSf-503D

TSf-503D

The TSf-503D, designed to evaluate the coefficients of friction using test methods such as pin-on-disk and ball-on-disk, offers four measuring routines in both directions of rotation with constant rotation speeds of the sample stage.
A full set of six weights is also included.

TSf-503R

TSf-503R

The TSf-503R has been specially designed to evaluate the coefficients of friction of cylindrical samples.
The sample holding device is tailored to customer-specific needs and it offers four measuring routines in both directions of rotation with constant rotation speeds, as well as a full set of six weights.

Functions and measuring routines of the Triboster TSf series

Biaxial balance technology

  • Minimization of the effects of inertia and other external forces to the load cell during the measurements, ensuring exact and reliable results.

Two-way-measurements

  • Measurement of the coefficients of friction in both ways of the stage travel.

Automatic contact probe lift-up function

  • Measurement of the coefficients of friction in only one way of the stage travel. The contact probe is lifted automatically after one stroke to avoid contact with the sample when the stage returns.

Up to seven measuring routines

Depending on the Triboster model, a variety of different measuring routines are available to ensure the most possible flexibility in determining specific characteristics of the samples. Available measuring routines are:

  • Continuous static friction: Measuring up to 50 data of coefficients of static friction in one stroke by stop-and-go movement of the stage
  • Standard repetition: Measuring the coefficients of friction repeatedly on the same measuring area in up to 12 cycles
  • Repetition dependency: Measuring the coefficients of friction repeatedly on the same measuring area in 100 to 10.000 cycles
  • Multi-sample: Measuring the coefficients of friction for different samples or different areas for one sample for easy comparison
  • Load-dependency: Measuring the coefficients of friction depending on different normal loads
  • Speed-dependency: Measuring the coefficients of friction depending on different speeds
  • Time-interval dependency: Analyzing the influence of adhesion to the coefficients of friction depending on up to 4 different contact times in one way, by use of the counterpart lift-up function and the stop and go movement of the stage

Paints & Coatings

  • The strength of plating layers and coated surfaces against scratching, continuous rubbing, sliding, etc.
  • Friction and wear of coated surfaces against each other

Medical

  • The friction of materials from artificial joints, valves of artificial hearts and implants
