Process connections for installation in small pipes
The matches for the process connections as well as the gaskets are not included in the scope of delivery of this
assembly. Welding adapter for Liquiphant M G1"- and Ingold process connections with associated o-ring sets
are available as accessories
Care should be taken by the user in the execution of the welding on the process side (suitable weld material,
welding radius > 3.2 mm, absence of pits, folds, crevices, …). As a general rule, the assemblies should be
installed in such a way that does not adversely affect their cleanability (3-A
®
requirements must be adhered
to). The required flush-mounting can be achieved by the connection Varivent
®
, Liquiphant type M G1" (+
weld-in adapter) and Ingold (+ weld-in adapter).
Neck tube length
The neck tube is the part between the process connection and the housing. It is normally made of a tube with
dimensional and physical characteristics (diameter and material) which are the same of the tube in contact with
the medium. The connection situated in the upper part of the neck allows for orientation of the terminal head.
The heating of the terminal head consequent to the process temperature is negligibly small if the process
temperature does not exceed the measuring range of TR44 and TR45.
• Standard neck tube diameter: 15 mm (0.6 in)
• Standard neck tube length:
– TR44: 82 mm (3.23 in)
– TR45: 85 mm (3.45 in)
