The L-Vis 520 Ex inline viscometer continuously displays the viscosity and temperature of petrochemicals, inks, crude oils, coatings and many more process liquids. It is ideal for monitoring suspensions and emulsions and is certified for use in hazardous areas.
L-Vis 520 Ex is available in two versions: L-Vis 520 Ex Smart Sensor combined with mPDS 5 evaluation unit or L-Vis 520 Ex Smart Sensor with a Remote Operating Terminal (ROT) which can be mounted at a distance of up to 250 meters from the sensor.
Certified for use in hazardous areas
- ATEX
- IECEx
- FM Approval Class I, Division 1 for USA and Canada
Designed for process
- Drops in pressure or flow rate do not affect the results
- Ensures consistent product quality and reduces reject product
- Uses a new measuring principle only available from Anton Paar
- Viscosity range covered from 1 mPa.s to 50,000 mPa.s
Longstanding experience in rheometry and viscometry
For more insight into material properties, L-Vis 520 Ex can be used in combination with an MCR rheometer, SVM 3000 Viscometer or Lovis 2000 M/ME viscometer
Installation directly in the pipe or stirring tank
- No bypass required, immersed directly in the liquid in the production line
- Easy to retrofit the inline viscometer into existing plants
Various communication possibilities with mPDS 5 and Remote Operating Terminal (ROT)
- Digital/analog in/output
- PROFIBUS DP
- PROFINET IO
- EtherNet/IP
- Modbus TCP
- DeviceNet
