Density Measurement with Uni-Probe LB 491
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
- Profibus PA
- Foundation Fieldbus
In addition the separate 4-20mA current output can always be used as alternative signal output.
