About KELAG Künzli Elektronik AG
KELAG Künzli Elektronik AG, based in Schwerzenbach (ZH), is a Swiss provider specialized in sensor technology and sensor systems. As an official partner of Vaisala and other selected manufacturers, the company supplies individual sensors, complete measurement systems, and engineering, design and integration services for meteorology, the environment, the process industry and industrial OEM. In the OEM division, own sensors – magnetic sensors (Reed, Hall, AMR), inclination and acceleration sensors – are produced in Switzerland and abroad and exported worldwide; standard products ex stock as well as individually configurable sensors from a modular kit system are available. The service portfolio covers consulting, project management, system integration and system replacement, installation and commissioning, repairs, calibration as well as maintenance and support. The family business, founded in 1975 by Kurt Künzli, is run by the second generation and is ISO 9001:2015 certified.
