A corresponding collar flange for DN 80 (ASME 3" or JIS 80) as well as
a suitable adapter flange are available for mounting VEGAPULS 61.
With the housing versions plastic, aluminium single chamber and
stainless steel, the collar flange can be placed directly over the
housing. With the aluminium double chamber housing, retroactive
mounting in this way is not possible - the mounting type must be
specified with the order.
Information:
The socket should be as short as possible and the socket end should
be rounded. Interfering reflections from the vessel socket are thus
minimised.
