GX's dust & splash-proof ability (up to IP54
level).
-
The
GX Balances' upper & lower case housings are designed so that
upper case housing entirely covers and overlaps the lower case when
it is assembled.
-
Little
dust can enter the balance through the pan-support-foot holes because
the shape of the pan-support-foot is designed to cover those holes.
It
is very rare for dust or foreign material to enter the balance from
the side direction because there is bosses at the outer-circumference
of the pan-support-holes.
-
The
balance unit is entirely covered with a standard dust cover when
it is not in use, so no dust can enter the balance.
-
The
AC adapter jack and the standard RS-232C's connector are located
at the lower part position on the GX main unit, so there is little
chance of dust invading through these areas. Additionally,
as double-protection, the RS-232C connector comes with a plastic
cover to keep out dust.
-
A&D
designed the keyboard overlay as a single sheet, so dust cannot
come enter the balance through the keyboard. Some of European
made balances have a problem with dust easily entering the
balance through the keyboard. It is one of the competition's
Achilles Heel's and a weak point.
-
In
the GX Balance class, no other competitors' balances are designed
to fully meet dust & splash-proof conditions. In an environment
full of dust, foreign material and oil-mist for long periods of
time, these foreign substances gradually invade the balance.
-
The
SHS is designed with the same clearance as the other A&D balances.
Mettler's "Monobloc" sensor
is made of one piece of metal in which a lever mechanism is fabricated
by a numerically controlled, fine wire-cutting electric-spark machining
way. Theoretically, one piece of metal eliminates instability
associated with different metals or mechanisms constructed of different
components or materials. The Mettler AB Series with their
Monobloc sensor has slits which are about 0.3 to 0.4 mm in width.
If dust or foreign material becomes lodged in these slits, the
sensor stops transferring force to the magnetic sensor accurately.
Thus the fine fabrication of narrow slits
in the metal has turns out to be the Achilles Heel for balances
designed with the Monobloc weighing cell in terms of price and serviceability.
It is very hard to repair the Monobloc once it malfunctions.
