Endress+Hauser Micropilot FMR67B - Temperature Limits

Technical data Micropilot FMR67B PROFINET with Ethernet-APL
76 Endress+Hauser
Ambient temperature limits The permitted ambient temperature (T
a
) depends on the selected housing material
(Product Configurator → Housing; Material →) and the selected process temperature range
(Product Configurator → Application →).
In the event of temperature (T
p
) at the process connection, the permitted ambient
temperature (T
a
) is reduced.
The following information only takes functional aspects into consideration. Additional
restrictions may apply for certified device versions.

In the case of devices with a plastic housing and CSA C/US approval, the selected
process temperature of
–40 to +80 °C (–40 to +176 °F) is limited to 0 to +80 °C (+32 to +176 °F).
