Explosion protection
Non-sparking, energy-limited "nA"
Dust, protection by enclosure "t"
Permissible ambient temperature
● For operation with or without HART
● For operation with PROFIBUS PA or
with FOUNDATION Fieldbus
At ≤ -10 °C (+14 °F), the display refresh rate of the display is limited. For basic devices with explosion protection: When
