We ensure that the tool deep in the cavern records all measured variables precisely and transmits them to the surface via the measuring cable, which is several kilometres long. The data is stored there and processed further by our colleagues. We develop the necessary electronic and mechanical components ourselves in Giesen near Hildesheim and have them manufactured by third-party companies in accordance with our specifications. The assembly is then carried out on our premises, as is the programming of the systems. We are constantly optimizing the existing elements of the tools to be able to measure under even more extreme conditions and are always developing new measuring methods so that we can offer additional services to our customers.
