The specifications apply to the standard configuration only (with FKM O-ring).
Maximum and minimum temperatures are dependent on the process connec-
tion, antenna and O-ring materials, and vessel pressure. For more detail, or for
other configurations, see
Maximum Process Temperature Chart
on page 119,
and
Process Pressure/Temperature derating curves
on page 120.
Note: The device nameplate lists the approvals that apply to your device.
