Note
[For Flowmeters] When Rosemount 644 Temperature Transmitter is
used, the Rosemount 644 should be used with Ex-certified associated
apparatus to establish explosion protection system that can be used in
explosive gas atmospheres. Wiring and terminals should comply with
the instruction manual of both Rosemount 644 and associated
apparatus. The cables between Rosemount 644 and associated
apparatus should be shielded cables (the cables must have insulated
shield). The shielded cable has to be grounded reliably in a non-
hazardous area.
4. Transmitters comply with the requirements for FISCO field devices
specified in IEC60079-27:2008. For the connection of an intrinsically
safe circuit in accordance with FISCO Model, FISCO parameters are
listed in the table above.
5. The product should be used with Ex-certified associated apparatus to
establish explosion protection system that can be used in explosive
gas atmospheres. Wiring and terminals should comply with the
instruction manual of the product and associated apparatus.
6. The cables between this product and associated apparatus should be
shielded cables (the cables must have insulated shield). The shielded
cable has to be grounded reliably in a non-hazardous area.
