Category 1G instruments
Temperature class Temperature on the antenna Ambient temperature on the elec -
tronics
T5 -20 … +42 °C -20 … +42 °C
T4, T3, T2, T1 -20 … +60 °C -20 … +60 °C
For applications requiring instruments of category 1G the process pressure of the media must be
between 0.8 … 1.1 bar. The application conditions when operating in the absence of explosive
mixtures can be found in the manufacturer information.

For applications requiring instruments of category 1G the process pressure of the media must be
between 0.8 … 1.1 bar. If the VEGAPULS PS61(*).C****P/K/F/L**** are operated at temperatures
higher than those specified in the above table, please make sure by means of appropriate measures
that there is no danger of ignition from the hot surfaces. The max. permissible temperature on the
electronics/housing should not exceed the values according to the above table.
Please make sure that the sensor also in case of failure does not generate heat itself. Responsibility
for safe operation of the equipment, with respect to pressures/temperatures of the materials used,
rests with the operator.
The prerequisites for operation in the absence of explosive mixtures can be found in the manufac -
turer specifications.
