Short
direct
EN1434
temperature
sensor
The
short
direct
temperature
sensor
has
been
designed
according
to
the
European
standard
for
heat
energy
meters
EN
1434
‐
2.
The
temperature
sensor
is
constructed
to
be
mounted
directly
in
the
measuring
medium,
i.e.
without
sensor
pocket,
by
which
you
obtain
an
extremely
fast
response
to
temperature
changes
from
e.g.
domestic
water
exchangers.
The
sensor
is
based
on
two
‐
wire
silicone
cable.
The
sensor
pipe
is
made
of
stainless
steel
and
has
a
diameter
of
4
mm
at
the
point,
where
the
sensor
element
is
placed.
Furthermore,
it
can
be
directly
mounted
in
many
of
Kamstrup’s
flow
sensor
types,
which
reduces
the
installation
costs.
The
short
direct
sensor
is
available
in
a
27.5
mm
version,
type
DS
27.5
mm,
and
in
a
38
mm
version,
type
DS
38
mm.
The
short
direct
sensor
can
be
used
in
PN16
installations
with
a
maximum
medium
temperature
of
150
°C.

As
it
appears
from
Figure 6
,
the
short
direct
sensor
DS
27.5
mm
can
be
mounted
by
means
of
an
R½
or
R¾
for
M10
nipple
in
a
standard
90
tee.
In
order
to
obtain
the
best
possible
serviceability
during
meter
replacement,
the
short
direct
sensor
can
be
placed
in
a
ball
valve
with
sensor
socket,
see
Figure 7
.
Ball
valves
with
sensor
sockets
are
available
in
G½,
G¾,
G1,
all
of
which
fit
the
DS
27.5
mm
sensor
as
well
as
in
G1¼
and
G1½,
both
fitting
the
DS
38
mm
sensor.
