Density Measurement with Uni-Probe LB 491

BERTHOLD Technologies GmbH & Co. KG: The measuring system Uni-Probe LB 491 is used for the non-contacting measurement of density and concentration on liquids, slurries or bulk materials. Connected to a velocity measurement, the Uni-Probe LB 491 can also be used for the online determination of mass flow.

The Uni-Probe LB 491 is a compact field device, combining both detector and evaluation in one single instrument. It provides interfaces for:

• HART
• Profibus PA
• Foundation Fieldbus

In addition the separate 4-20mA current output can always be used as alternative signal output.
