Transformer Oil - Transformers

Transformer Oil

An optical exchange window and reading unit is integrated in transformers to monitor the oxygen content of transformer oils. A system with excellent long-term stability (10 years shelf life), an oil tight fitting and tolerant to temperatures from - 40 °C to + 80 °C had to be built, so it would work in desert as well as in polar climate.

Zero Gravity Experiments - Satellite in Orbit

Zero Gravity Experiments

Due to their small outer dimensions an electro-optical module (EOM) and non-invasive sensor spots were used to monitor oxygen in a closed ecosystem in space. The unit had to be vibration resistant to stand starting and landing procedures of the satellite mission.

O2 Sensor Spots SP-PSt3

Cellular Assay - OxoPlate and HydroPlate

Cellular Assay / Cellular Fitness

Disposables with integrated sensors and the respective read-out electronics have been provided for implementation in a high throughput cell culture analysis system. Multiple culture parameters and cellular fitness can be monitored.
