3.3.2 Installing the Promag H sensor
The Promag H sensor is supplied to order, with or without pre-installed process connections.
Pre-installed process connections are secured to the sensor with hex-head threaded fasteners.
"
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  ä 120.

Fig. 20: Promag H process connections (DN 2 to 25 / 1/12 to 1", DN 40 to 100 / 1½ to 4")
A: DN 2 to 25 (1/12 to 1") / process connections with O-rings:
Welding flanges (DIN EN ISO 1127, ODT / SMS), flange (EN (DIN), ANSI, JIS), flange PVDF (EN (DIN), ANSI, JIS), external
and internal pipe threads, hose connection, PVC adhesive fitting

coupling (DIN 11851, DIN 11864-1, SMS 1145), flange DIN 11864-2
C: DN 40 to 100 (1½ to 4") / process connections with aseptic gasket seals:
Welding nozzles (DIN 11850, ODT / SMS), Clamp (ISO 2852, DIN 32676), L14 AM7),
coupling (DIN 11851, DIN 11864-1, ISO 2853, SMS 1145), flange DIN 11864-2
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 / 5.2 lbf ft).
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
gasket 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  ä 120.
