Note 1: FISCO parameters apply to both Group IIC and IIB.
Note 2: [For Flowmeters] When 644 temperature transmitter is used, the 644
temperature transmitter 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 644 temperature
transmitter and associated apparatus. The cables between 644 temperatures transmitter
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 dev
ices specified in
IEC60079-
27:2008. For the connection of an intrinsically safe circuit in accordance wi
th
FISCO
Model, FISCO paramete
rs are listed in the table above.
5.

ion system that can be used in explosive gas atmo
spheres. Wiring and
terminals should comply
with the instruction manual of the product a
nd 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 b
e grounded reliably
in a non-hazardous area.
7.
End users are not permitted to change any intern components but to settle the probl
em
in conjunction w
ith the manufacturer to avoid damage to the product.
