Service & reparation Request a quoteThe Linseis TEG Tester is a measurement system for temperature dependent conversion efficiency evaluations for thermoelectric generators (TEGs). Due to the temperature setting point, a gradient is applied across the thermoelectric device and the heat flow through the reference block into and out of the TEG is measured.
The generated voltage and current is scanned on different points, in less than 10 msec, to get the I-V curves or operate the TEG under a dynamic load. Hence it is possible to calculate the efficiency and track the maximum power point using the perturb and observe method.
Applications:
- Performance testing of thermoelectric modules
- Evaluation of maximum power generation and conversion efficiency
- Long-term lifespan testing under load and thermal cycling
Features:
- Automatic mechanical load with pressure compensation
- Different modes of operation (CC, CV, FOC, MPPT, P&O)
