A.1.5 Environmental requirements

Ambient temperature limits

Operation: –40 to +140 °F (–40 to +60 °C)

Storage: –40 to +140 °F (–40 to +60 °C)

Display responsiveness decreases, and display may become difficult to read, below –4 °F (–20 °C). Above 131 °F (55 °C), some darkening of display may occur.

If possible, install the transmitter in a location that will prevent direct exposure to sunlight.

Different ambient temperature requirements may apply when installing the transmitter in a hazardous area. Refer to the approval documentation shipped with the transmitter or available on the Micro Motion web site.

Humidity limits

Relative humidity between 5 and 95%, non-condensing at 140 °F (60 °C)

Vibration limits
