Sensirion take to space supporting the WOBBLE2 project
21st March 2025

Sensirion is supporting the WOBBLE2 project of the Berlin Experimental Astronautics Research Student e.V. (BEARS e.V.) with the high-precision SLF3S-4000B sensor.
The dedicated team of students from the Technical University of Berlin has qualified for the 15th cycle of the REXUS/BEXUS program, which allows them to test their experiments on sounding rockets.
Innovative technology for space exploration
The WOBBLE2 project (Weightless Observation of Behaviour with Berlin Liquid Guidance Experiment 2) aims to test innovative tanks for satellites. At the heart of the experiment are Propellant Management Devices (PMD), which ensure that fuel is transported to the outlet in zero gravity. Using additive manufacturing techniques (metal 3D printing), the team is developing new PMD designs that optimally utilise the capabilities of this modern technology.
Precise measurements with the SLF3S-4000B Sensor
Sensirion supports the WOBBLE2 project with the SLF3S-4000B sensors, which is used in the experiments to enable precise measurements of fluid behaviour. This ensures that the team's experiments are conducted at the highest technological level and contributes to the advancement of space technology.
Successful training week in Sweden
Six students from the team travelled to the ESA rocket base in Esrange, northern Sweden, in February 2024 to take the first step towards the rocket launch in March 2025. At temperatures of -30°C, they received valuable feedback from an expert panel and participated in an exciting program of lectures and tours. Over the course of the year, they have now completed further milestones and have been preparing for the launch in Sweden since Monday, 3 March 2025.
