Temperature
probe
2
The
temperature
measuring
probe
is
made
of
a
plug,
a
wire,
a
handle

and
a
metal
tube
with
an
outer
diameter
of
Φ5mm×220mm.
The

front
end
of
the
tube
is
packaged
with
a
temperature
sensor,
which
is

suitable
for
measuring
the
temperature
of
materials
and
clinker.
Temperature
measurement
line

The
embedded
temperature
measuring
line
is
made
of
a
plug,
a
wire

and
a
temperature
sensor,
which
is
suitable
for
measuring
the

internal
temperature
of
the
concrete.
Each
temperature
measuring

line
can
measure
the
temperature
at
one
point,
and
the
temperature

measuring
point
can
be
arranged
arbitrarily
during
the
construction.

In
order
to
facilitate
layered
temperature
measurement,
the
plug
of

each
temperature
measurement
cable
has
a
label
affixed
with
a

corresponding
length
specification.

and
temperature
probe
to
measure
the
temperature

of
the
material
Insert
the
plug
of
the
temperature
probe
into
the
socket
of
the
host,

press
the
power
switch,
and
insert
the
metal
claw
of
the
temperature

probe
into
the
object
to
be
measured,
the
insertion
depth
is
not
less

than
1/2
of
its
length,
and
the
temperature
data
is
read
on
the
host
in

about
two
minutes.
When
measuring
the
temperature
of
the
mixture,

in
order
to
avoid
excessive
impact
between
the
temperature
probe

and
the
hard
objects
in
the
mixture
and
affect
the
service
life,
a
metal

rod
can
be
used
to
reserve
a
hole
in
the
mixture,
and
then
the

can
be
inserted
into
