6.1.2 Requirements from environment and process
Ambient temperature range
Measuring device • –40 to +60 °C (–40 to +140 °F)
• –50 to +60 °C (–58 to +140 °F) (Order code for "Test, certificate", option JM
Safety Barrier Promass 100 –40 to +60 °C (–40 to +140 °F)
‣
If operating outdoors:
Avoid direct sunlight, particularly in warm climatic regions.
System pressure
It is important that cavitation does not occur, or that gases entrained in the liquids do not
outgas.
Cavitation is caused if the pressure drops below the vapor pressure:
• In liquids that have a low boiling point (e.g. hydrocarbons, solvents, liquefied gases)
• In suction lines
‣
Ensure the system pressure is sufficiently high to prevent cavitation and outgassing.
For this reason, the following mounting locations are recommended:
• At the lowest point in a vertical pipe
• Downstream from pumps (no danger of vacuum)

Heating
NOTICE
Electronics can overheat due to elevated ambient temperature!
‣
Observe maximum permitted ambient temperature for the transmitter (  19).
‣
Depending on the fluid temperature, take the device orientation requirements into
account .
Heating options
If a fluid requires that no heat loss should occur at the sensor, users can avail of the
following heating options:
• Electrical heating, e.g. with electric band heaters
• Via pipes carrying hot water or steam
• Via heating jackets
