Cảm biến đo mức bức xạ Uni-Probe LB 490 L Berthold
Universal field detectors for various level measurement applications
Uni-Probe LB 490 is used for non-contact measurement of continuous level and as a level switch. The compact field device integrates detector and transmitter in one device. The level gauge is inexpensive, reliable, and accurate, and comes with Berthold's standard high sensitivity allowing for low source activity.
Technological Highlights
Simple and intuitive operation
• - Inexpensive and solid system for standard applications
• - Compact field device with integrated transmitter
• - Multiple digital and analogue outputs and inputs make the Uni-Probe universally adaptable
State of the art technology
• - Communication via HART, Foundation Fieldbus or Profibus PA
• - Communication can be switched over from Bus to HART at any time
• - High operational safety, FMEDA with SFF 96%
Features for high demands
The level measuring system Uni-Probe LB 490 has interfaces for HART, Profibus PA and Foundation Fieldbus.
Even if the LB 490 level measurement 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 be used as a signal output (e.g. for a remote display).
Easy measurement on extremely thick walls
Large containers with extremely thick walls require very high activities. When using the SuperSENS, the source activities can be significantly reduced.
If you have measurements with point detectors and you are faced with the decision to replace the now weak sources, switching to SuperSENS detectors can push back the replacement of the source, as the higher detector sensitivity extends the useful life of the source.
