Level switch measurement with Uni-Probe LB 490

The universal field device for various applications

Uni-Probe LB 490 is used for non-contact measurement of levels and limit values. The compact field probe combines detector and evaluation in one device. The level gauge is inexpensive, reliable and accurate and comes with very low source activity.
The level measurement Uni-Probe LB 490 has interfaces for HART, Profibus PA and Foundation Fieldbus.

Even if the level measurement LB 490 is used in Profibus or Fieldbus systems, it is always possible to switch to HART communication if required. The separate 4-20mA current output can alternatively be used as a signal output (e.g. for a remote display).
