3.1.3 CONTACTS REPLACEMENT
Marposs has developed interchangeable contacts, because these parts are subject
to wear. For their replacement, a set of special wrenches (see Table “Wrenches for
contacts”) is provided: they vary on the basis of the technical specifications of the plug
gauge. The table below indicates and represents the specifications of the contacts and
the method with which the contacts are fastened to the measuring armsets: the methods
vary in relation to the application (for through/blind bores or superblind bores) and/or to
the diameter class.
ATTENTION
:
(*) The positioning of the contacts and/or extensions on the measuring armset depends
on the nominal diameter of the nosepiece, because the contact must NOT protrude more
than the maximum value expressed in the table.
(**) The values are only referred to configuration with standard clearance nosepiece/piece, for
under/over-sized configurations contact the nearest MARPOSS office, in order to get detailed
information on the application.
(***) The pipe wrenches to be applied to assembly/disassembly the contacts are in conjunction
with the application itself (through, blind, super-blind or BC), by the contacts building material
and by the diameter range of the plug gauge. In the table chart “CONTACT WRENCHES” are
expressed the wrenches according to the features mentioned above.

The contacts are an integral part of the
measuring armset, so they cannot be
disassembled.
