WARNING
• Installation shall only be performed by qualified personnel and in accordance with local
governing regulations.
• Handle the device using the enclosure, not the process connection tag, to avoid
damage.
• Take special care when handling the threaded PVDF and Flanged encapsulated
antennas. Any damage to the antenna surface, particularly to the tip/lens, could affect
performance.
• Materials of construction are chosen based on their chemical compatibility (or inertness)
for general purposes. For exposure to specific environments, check with chemical
compatibility charts before installing.
Note
•
For European Union and member countries, installation must be according to ETSI EN
302372.
•
Refer to the device nameplate for approval information.
