Successful cooperation in the field of renewable energy sources continues


Sensor solutions of Hamilton Bonaduz AG are applied in upcoming projects of the Karlsruhe Institute of Technology (KIT)

(Bonaduz, 06/21/2016) – The technical biology field of the KIT (Karlsruhe Institute of Technology) sealed in the course of various successfully completed projects the further collaboration with Hamilton Bonaduz AG. In this context, the institute implemented the redox sensor EasyFerm Plus ORP Arc in the field of sustainable and efficient biosynthesis pathways. In this way, the sensor experts proved once again the outstanding customer relationship that continues now persistently for over ten years. The main focus of the research team is on the development of biomass – a renewable source of energy that operates without fossil fuels. The biomass required can be obtained within small reactors by means of synthesis gas fermentation. Using the EasyFerm Plus ORP Arc sensor is important since a redox potential beneath a certain threshold is needed. In this way, the reliable growth of the anaerobic microorganisms that are inserted during the synthesis process is secured. The robust redox sensor is stable against the harsh conditions in bioreactors and is therefore perfectly suited for demanding applications in the chemical industry. The sensor is additionally pressurized – in this way potential clogging as well as penetration of the medium in the reference electrolyte can be prevented. The used Everf-F reference system allows the sensor to stay free of silver and precipitation and ensures consequently a high durability. The EasyFerm Plus ORP Arc sensor provides furthermore drift free and reliable measurements in the range of -1500 mV and up to +1500 mV – even after sterilization and autoclaving processes up to 140 °C or CIP cycles. A micro transmitter saves all relevant data, including calibration and standard information, in the Arc sensor head. Research group leader Dr. rer. nat. Anke Neumann of the KIT sums up: “we were particularly impressed with the user friendly operation, the high durability as well as the robust design of the sensors” and adds that the institute is going to bank also for future projects on the solutions of the Swiss experts.
