Technical Data
The 5606 and 5607 Full
Immersion PRTs are designed
to perform in extreme environments where both the transition
junction and the lead wires are
required to withstand temperatures covering the entire
operating range of the probe.
(“Immersion” in this case simply
means exposure to temperatures other than ambient and
does not necessarily refer to the
medium to which the PRT and
its components are subjected.)
Applications where “full
immersion” of probe, transition junction, and lead wire is
required can include calibration
or validation of sensors used in
laboratory or bio freezers, walkin refrigerators, autoclaves,
ovens, stability test chambers,
furnaces or incubators. Other
applications might include IQ/
OQ/PQ qualification procedures,
temperature mapping, or data
logging in temperature controlled spaces or environmental
chambers.
The 5606 is just two inches
(50 mm) in length with a sheath
diameter of 1/8 inch (3.1 mm).
Since it can be fully immersed
over its entire temperature
range, you don’t have to worry
about calculating minimum
immersion depth—immerse the
entire probe, transition junction,
and lead wires, in either noncorrosive liquids or dry mediums
ranging from –200 °C to 160 °C.
The 100 W precision sensing
element (alpha = 0.00385) is
specially constructed to prevent
the ingress of moisture while
achieving calibration accuracies as good as ± 0.05 °C. You
get both accuracy and flexibility built into a small, durable
package.
The lead wires of the 5606
are made of single-conductor
enameled copper wire which
prevents moisture from wicking to the sensing element as
it would if a more common,
stranded lead wire were used.
The diameter of the lead wire is
no greater than 0.2 mm, making
it easy to run lead wires through
a freezer door to your readout or
transmitter with effectively zero
energy loss. The 5606 has been
proven in common heat transfer fluids such as silicone oil,
mineral oil, ethanol, and even
liquid nitrogen with no degradation of the transition junction
seal or lead wire insulation.
Are you performing calibrations or verifying the accuracy
of sensors used in ovens or
furnaces? The 5607 has been
designed specifically for your
application. Intended to be used
in dry mediums only, the 5607
can be fully immersed over a
temperature range of 0 °C to
450 °C. There isn’t another PRT
on the market that can be fully
immersed over this range and
remain as stable and accurate
(± 0.055 °C). The lead wire
of the 5607 is shielded with
braided stainless steel and connected to the transition junction
with a strain relief spring.

They can also help you determine which readout and probe
termination are best suited for
your application or help you
select the right calibration for
your probe.
