9 Operating conditions

9.1 Process conditions
The pressure and temperature ratings presented in this section represent the
design values for the devices. For individual applications (e.g. marine
applications with option S2x) further limitations may apply according to the
respective applicable regulations. For details see chapter Application and
industry related standards [} 172] under the heading Marine approvals.
In this chapter, all values related to pressure are gauge pressure values.

9.1.1 Process fluid temperature range

Allowed process fluid and ambient temperature ranges in hazardous areas
depend on classifications defined by applications, refer to Temperature
specification in hazardous areas [} 46].
For SITRANS FC7x0 the following process fluid temperature ranges are available:
