Temperature control of the test contact and temperature measurement
The manufacture of practice-relevant thermal operating conditions for friction contacts is absolutely essential for investigating lubricants, additives and coatings – as well as for the overall function of the tribocontact.
Dynamic heating or cooling from -45° to 1000°C
Depending on the application, test contacts can be temperature-controlled on our test systems from -45°C to 1000°C.
Dynamic setpoint profiles enable both defined heating as well as cooling of tribocontacts and lubricants.
Highest precision with model-based temperature control
We use model-based temperature control for high-precision achievement of setpoint temperatures without control deviations (e.g. overshoots). For each test setup, a precise thermal model of the test system can be integrated into the controller. This ensures permanent maintenance of the selected test temperature without deviation or distortion. We apply this principle of model-based control both in the standard temperature range as well as in low- and high-temperature options, and in the rotation module. The reference point for controlling and measuring both heating and cooling is located on the bottom of the test specimen.
- Temperature control of the test contact is important primarily when investigating lubricants, additives and coatings
- Model-based temperature control for high-precision maintenance of selected test temperature
- Dynamic setpoint profiles for defined heat-up and cool-down during test
- In addition to heating the test specimen, the atmosphere in the test chamber surrounding the test body can also be heated to approximately 700°C. > Learn more
- Particularly when working with components, it is advantageous to have the option of measuring the temperature close to the friction point.
- Lubricant development with model-based temperature control allows the investigation of functional properties, the application range of additives, and more.
- Model-based temperature control continues to allow use of the setpoint temperature on the top of the test body as the reference temperature. This means that heating can be controlled by surface temperatures that have developed due to friction.
