12 Direct Mounting With Threaded Connection - Endress+Hauser Solimotion FTR20 Technical Information

Direct mounting with threaded
connection
14
The simplest mounting method is by screwing into the process wall� To do this, a corresponding
internal thread (Rp 1½, 1½ NPT or G 1½) must be available in the process�
• Weld-in adapters of type FAR52-A*, with corresponding internal thread, are available as
accessories (→ 31).
• If the internal threads available in the process wall are different (R 2 to R 4 or 2 NPT
to 4 NPT), additional screw-in adapters of type FAR52-B* are available as accessories
(→ 31).

With direct mounting in the process wall, it must be ensured that the front edge of the process
connection is flush with the internal edge.

• If the process connection is not screwed far enough into the process wall (1), there is a risk that
material will collect in front of the FTR20 and cause attenuation of the microwave signal�
• If, on the other hand, the process connection is screwed too far into the process (2), there is a risk
of damage due to large falling product pieces�
When using the G 1½ -process connection (standard thread to ISO 228-1, hexagon SW55)
with integrated counter nut, the devices can be flush mounted especially easily, as a parallel
thread is used�
