Characteristic
4 … 20 mA/HART output, measuring range up to 20 m, accuracy ±2 mm, Ex approval optional, on-site display and 3-button operation
Application
VEGAPULS 31 is the ideal sensor for non-contact level measurement of liquids and bulk solids in simple applications. It is particularly suitable for use in water treatment, storage tanks with acids, lyes and additives in all industrial areas, or for measuring levels in plastic tanks from the outside through the tank wall. In bulk solids the sensors are used in small bulk solids silos or open containers.
Benefits
- Exact measurement results independent of medium properties and process conditions
- On-site display for easy level control
- Maintenance-free operation due to non-contact 80 GHz radar technology
