In modern industrial and environmental processes, precise measured values determine efficiency, safety and quality. UNION Sensors develops and produces high-performance sensors that are specially designed for demanding applications in maritime and limnic environments. Our sensor solutions deliver stable, resilient and high-resolution measurement data – even under extreme conditions such as salt water, high pressure, flow or strongly fluctuating water chemistry.

With decades of experience in industrial measurement technology and a clear focus on innovation, UNION Sensors sets new standards in water and process sensor technology. Our technologies combine mechanical robustness, maximum precision and intelligent signal processing to reliably enable measurements even in dynamic and challenging waters.

In the maritime sector, our sensors are used in coastal waters, offshore plants, research platforms and shipping, among other applications. They record relevant parameters such as temperature, conductivity, oxygen, turbidity or nutrients and provide important data for environmental monitoring, process control and maritime research.

In the limnic sector – for example in lakes, rivers, reservoirs, aquaculture or drinking water reservoirs – our sensors support the monitoring of water quality, the ecological assessment and resource management. They help to identify changes at an early stage and protect water sustainably.

Our Mission: Sensor Technology. Redefined.
We are reinventing sensor technology – more intelligent, more powerful and field-tested. On this page you will find an overview of our sensor products, their areas of application and the technological advantages that make UNION Sensors a leading provider in maritime and limnic measurement technology.
