Each
stirrer
is
equipped
with
an
opto-sensor
for
speed
monitoring,
and
a
speed
limiter
circuit
that
prevents
hazardous
operation
when
the
load
is
suddenly
removed.
The
power
required
to
effectively
stir
a
fluid
is
affected
by
the
torque
load
on
the
stirrer
which
is
dependent
on
the
capacity,
type
and
viscosity
of
the
fluid.
The
speed
of
the
stirrer
decreases
as
the
torque
load
increases
and
vice
versa,
unless
the
power
delivered
changes
accordingly.
For
Newtonian
fluids
like
water,
the
viscosity
remains
constant
during
stirring.
General
pur-
pose,
normal
stirrers
are
ideal
for
this
kind
of
fluids.
For
some
fluids
like
oil
and
clay,
the
viscos-
ity
changes
during
the
stirring
process,
mak-
ing
it
necessary
to
adjust
the
power
to
main-
tain
a
constant
speed
during
the
stirring.
Hanna
Auto-Speed
stirrers
(HI
31X
series)
are
designed
with
automatic
feedback
control
to
maintain
constant
speed
when
the
torque
load
changes
and
are
therefore
ideal
for
stir-
ring
non-Newtonian
fluids
where
the
viscosity
changes
during
stirring.
They
are
also
ideal
for
mixing
applications
where
one
solution
is
added
to
another
which
changes
the
capacity
and
thereby
the
torque
load
on
the
stirrer.
The
Auto-Speed
stirrers
maintain
a
constant
stirring
speed
during
the
mixing
up
to
the
full
capacity
of
5
liters.
They
can
also
be
used
with
Newtonian
fluids
up
to
a
capacity
of
5
liters.
