3.5 Pressure and temperature ranges

WARNING!
The process connection temperature range must agree with the temperature limits of the
gasket material. The operating pressure range is subject to the process connection used and the
flange temperature.
Figure 3-3: Pressure and temperature ranges
1 Temperature at the process connection
Non-Ex devices: The temperature range depends on the type of antenna, process connection and the seal material.
Refer to the table that follows.
Devices with Hazardous Location approvals: see supplementary instructions
2 Ambient temperature for operation of the display
-20...+70°C / -4...+158°F
If the ambient temperature is not between these limits, then it is possible that the display screen will not operate tem-
porarily. The device continues to measure level and send an output signal.
3 Ambient temperature
Non-Ex devices: -40...+80°C / -40...+176°F
Devices with Hazardous Location approvals: see supplementary instructions
4 Process pressure
Depends on the type of antenna and process connection. Refer to the table that follows.
Maximum process connection temperature and operating pressure
Lens DN40, PEEK
Lens DN70, PEEK
1 If the process connection temperature is more than +150°C / +302°F, the device has a distance piece. For more data
about the overall dimensions of the device, refer to the "Dimensions and weights section".
For more data on pressure ratings, refer to
128.
