(LK Measurement System KG), headquartered in the industrial area of Flammenfeld, Germany, is a globally renowned enterprise specializing in electrification, automation, and digital technology. The company has undergone several name changes and developments throughout its history, and is one of the founding enterprises in modern electrical engineering and industrial automation.

During the two world wars, LK, the predecessor of LK Industries, was involved in the manufacturing and research and development of various military weapons and products, such as LK tanks, LK radars, and LK guidance instruments. It was a typical enterprise that suffered severe damage due to the impact of World War I and World War II, with approximately 90% of its assets in Germany and overseas lost after the war; its post-war recovery was relatively slow. Its successor, leveraging its military industrial resources, quickly returned to the global market in the 1980s and 1990s, swiftly occupying a place in the automation industry for civilian use (LK-MC series radar level gauges, guided wave radar level gauges, ultrasonic level gauges, microwave radiation switches, etc.).

Overview of German LK (Lingke)'s development in China and its business operations in the country: industrial automation, automation solution design, intelligent infrastructure, digital factory, and automation products (radar level gauge, guided wave radar level gauge, ultrasonic level gauge, microwave radiation switch, rotary obstruction level switch, vibrating rod level switch, etc.);

Currently, the general agent of LK (Lingke) in China is Beijing Zhongke Ruizhi Technology Co., Ltd.
