10.1.4 Operating conditions: Environment
Ambient temperature range Ambient temperature for the transmitter: -40 °C ... +80 °C (-40 °F … +176 °F)
The functionality of the LCD display may be limited for temperatures
Ta+60 °C.
A weather protection cover should be used for outdoor operation if the instrument is exposed to
direct sunlight.
Ambient temperature limits If temperatures above 80 °C are present at the process connection, the permitted ambient
temperature is reduced according to the following diagram (temperature derating):
