Installing the Promag H sensor

The Promag H is supplied to order, with or without pre-installed process connections. Pre-installed
process connections are secured to the sensor with 4 hex-head screws.
Caution!
The sensor might require support or additional attachments, depending on the application and the
length of the piping run. When plastic process connections are used, the sensor must be additionally
supported mechanically. A wall-mounting kit can be ordered separately from Endress+Hauser as an
accessory. → Page 133

Seals
When installing the process connections, make sure that the seals are clean and correctly centered.
Caution!
• With metallic process connections, you must fully tighten the screws. The process connection
forms a metallic connection with the sensor, which ensures a defined compression of the seal.
• With plastic process connections, note the max. torques for lubricated threads (7 Nm). With
plastic flanges, always use seals between connection and counter flange.
• The seals must be replaced periodically, depending on the application, particularly in the case of
molded seals (aseptic version)! The period between changes depends on the frequency of cleaning
cycles, the cleaning temperature and the fluid temperature. Replacement seals can be ordered as
accessories. → Page 133
