How It Works

The TORRIX sensor uses magnetostrictive technology to measure liquid levels with extreme precision. A float containing a magnet moves along the probe, and the sensor detects its exact position using time-based signal measurement.

• Measures fill level and interface simultaneously (dual float option)
• Detects even small differences in liquid properties
• Maintains accuracy despite turbulence or vibration

Applications

The TORRIX level sensor is designed for a wide range of industries and use cases:

• Storage tanks and bulk liquid containers
• Chemical and petrochemical processing
• Interface measurement (e.g. oil/water separation)
• Pilot plants and R&D systems
• Manufacturing and process automation
