  • Entry
  • Associated product(s)

Problem/FAQ:
I require the SIL 2 rating on my LR250 Radar device. Do I need to order the –Z C20 option with corresponding MLFB in order to use this in a SIL 2 approved application?

Solution:  
Yes, in addition to the MLFB listed in the Certificate of Conformity, the SITRANS LR250 device must still be ordered with the C20 option. The Declaration of Conformity can be downloaded via the PIA Selector Tool, under Certificates. Also, the Declaration of Conformity as well as the Safety manual can be downloaded.
