Sanitary Intelligent Level Switch (SIS) The SIS Sanitary Intelligent Level Switch provides reliable high‑ and low‑level detection for tanks and pipelines across a wide range of production processes. Its compact, lightweight design makes it easy to transport and enables fast installation, even in tight spaces or challenging operating environments. Engineered for CIP and SIP cleaning applications, the SIS switch offers customizable surface roughness (Ra) levels to meet specific hygiene requirements. This makes it an ideal choice for pharmaceutical manufacturing, food and beverage processing, and other industries that demand strict sanitary standards. Key Features Accurate high/low level alarm for tanks and pipelines Compact design for easy handling and quick installation Compatible with CIP/SIP cleaning processes Adjustable surface roughness (Ra) to meet hygiene requirements Suitable for pharmaceutical, food, and sanitary processing applications
The SIS Intelligent Level Sensor operates using advanced capacitive and electronic signal‑processing technology to detect the presence or absence of liquid media in sanitary process environments. When the sensor’s probe comes into contact with a liquid, it measures changes in dielectric properties and instantly converts them into a stable, accurate switching signal.
Its intelligent design ensures reliable performance even with varying viscosities, foams, or process conditions. The sensor continuously monitors the medium and provides a precise high‑ or low‑level alarm output to prevent overflow, dry‑run, or process interruption.
