About Kümago
Kümago Nexus GmbH is a company based in Düsseldorf specializing in industrial sensor and measurement technology. The portfolio includes industrial pressure sensors and transmitters (including MEMS, piezoresistive and silicon-resonant types with up to ±0.01 % FS), flow, level, temperature, infrared and gas sensors as well as pressure calibration technology such as dead weight testers, hand pressure pumps and pressure comparators. In addition, Kümago offers sensor components such as diaphragms, diaphragm capsules, glass feedthroughs (glass-to-metal seals), isolators and valve blocks, manufactured in corrosion-resistant materials such as 316L, titanium, tantalum, Hastelloy and Inconel. As the exclusive representative of Chinese manufacturers (including CFSensor, Creatwit, Sentinel) in the EU, Kümago provides OEM customization, technical support and pre-sales service. Target industries include automation technology, calibration laboratories, aerospace, the process industry, pharmaceuticals as well as food and energy.
