1. The Rosemount 2160 may be used in a hazardous area with
flammable gases and vapors with apparatus groups IIC, IIB and IIA,
and temperature classes T1 to T5. The temperature class of the
installation will be determined from the highest process or ambient
temperature. The temperature class of the installation will be
determined from the highest process or ambient temperature.
2. It is a special condition of the certification that the temperature of
