All our test benches requiring a vacuum chamber are equipped with bulkhead feed-throughs. These enable us to retrieve all the necessary data (Temperature/Power/Position/Pressure…) for the tests to be carried out correctly:

The test benches feature temperature-controlled trays (35K to 350K) on which components are thermally cycled.
Absolut System ensures cycle repeatability, with precise regulation of the cooling and heating phases, and stabilization at predefined levels. The number of cycles, temperature steps and durations are fully customizable to suit test requirements.
Key Points
- Temperature range: 35K to 350K
- Step control (slope management)
- Reduction of parasitic fluxes by radiative shielding
- Testing of all possible sample types
Technical capabilities of benches
- Vacuum level: 1.10-6mbar
- Maximum speaker diameter: 1m
- Maximum diameter of cold trays: 800mm
- Minimum temperature: 30K
- Maximum température: 350K
- Maximum slope: 100K/minute (taille d’échantillon réduite)
Support
Parasitic flux management: aluminum radiative screen plus MLI.
Attachment: M4 threaded holes with a 20mm by 20mm pitch as standard, or any other option on request.
Acquisitions
- 20 measurement channels (pt100 temperature sensors).
- Maximum and minimum temperature safety management.
