Thermocouple Wire
and Thermocouple
Extension Wire
Technical Data
How to Select Wire to Suit
Your Requirements
The following information will
acquaint you with some of the
nomenclature involved with
thermocouple wire and
thermocouple extension wire.
By spending a few minutes
reading this information orders
can be placed quickly and
accurately.

Thermocouple Wire or
Thermocouple Extension Wire
There are some significant differences between the wire used to
actually measure temperature and
the wire used to carry the
millivoltage signal to an instrument.

Duplex Conductor Insulation
This item lists the overall insulation
when one is used. Some constructions which have no overall insulation
use this area to describe the
duplexing method—i.e. twisting,
“ripcord”, etc.

The most obvious difference is the
color-code used to identify the wire
itself. In most cases, thermocouple
grade wire is identified by its overall
brown color. The exceptions in the
SERV-RITE wire product line are the
very high temperature yarns such as
those used in the SERIES 301 and
350. Of course, the overall color
code is not used when there is no
overall covering as in SERV-RITE
wire SERIES 505, 511 and 314.
The working differences between
the two wires is that the thermocouple “extension” wire is not
calibrated above 204°C (400°F). The
temperature rating of the insulations
used on some extension grade wire
exceeds this 204°C (400°F)
temperature. This is to allow the wire
to survive occasional contact with
hot parts or furnace walls.
The following explains the meanings
of the terms used in the tables of
this section.

Temperature Rating
Most constructions are rated for both
continuous use and for single reading applications. The continuous use
temperature is considered to be the
highest temperature at which that
particular construction will survive
indefinitely. The single reading
temperature has been determined
by actual tests. Each insulation
system will perform differently when
exposed to this temperature.
Generally, the construction will
perform at this temperature and
produce an accurate reading.
However, after exposure to this
temperature, the wire will exhibit less
flexibility and/or abrasion resistance.
Because of this, it is unlikely that the
wire could be removed from the
application and then replaced after
exposure to the “single reading
temperature.”

SERV-RITE® Wire and Cable

Single Conductor Insulation
This item identifies the type of
insulation used on the individual
thermoelements. Certain part
numbers use a combination of
insulations. When there is a
combination, the insulations are
listed in their order of application.

How to Select Wire to Suit
Your Requirements
ASTM E 230 Color Code
Generally, SERV-RITE wire has
color codes wherever possible.
The exceptions are the high
temperature yarn constructions
such as the SERIES 301 and 350.
Color coding of the SERIES 511 and
512 is accomplished by including a
colored thread or “tracer” under the
tape.
Physical Properties
Abrasion Resistance is rated fair,
good, or excellent and is based on
the wall thickness of the construction
and how well it survives with other
insulations of similar thicknesses.
The 511 SERIES receives an
excellent rating because the thin wall
of polyimide tape will survive better
than almost any other insulation
applied in the same wall thickness.
The “absolute” abrasion resistance
of a construction will depend not
only on the type of insulation but on
thickness at which it is applied.
Moisture Resistance ratings are
given for the wire in the “as
received” condition. In the case of
fiberglass insulated wire, the
moisture resistance is achieved by
the use of impregnations or spirally
applied tapes called moisture
barriers. The impregnations and/or
tapes will burn off at temperatures
below the upper useful operating
temperatures of the fiberglass. The
thermoplastic insulations (PVC and
the fluoroplastics) and the polyimide
insulated constructions will maintain
their moisture resistance up to their
“continuous” temperature rating.

Chemical Resistance ratings are
given as they relate to most
common chemicals. These ratings
apply to the insulation types and not
necessarily to the type of
impregnation used. Consult factory
for specific applications.

UL Listed PLTC Wire And Cable
Watlow offers UL listed SERV-RITE
thermocouple and extension wire
and cable for PLTC (Power Limited
Tray Cable) applications. The
following insulation SERIES have
these approvals:
• 502
• 507
• 509
• 510
• 900
• 1000
All these insulation SERIES have the
following physical characteristics:
• UL listed Type PLTC—300 Volt
®

Stainless Steel Wire Braid (S)
This, the most popular of the overbraids, uses 300 series stainless
steel and is available on virtually all
standard SERV-RITE wire offerings. It
is an economical method of
extending the life of thermocouple
and extension wire. Several of our
standard wire items are available
from stock with a stainless overbraid.
Non-stock items are available on a
special order basis.
Alloy 600 Wire Braid (N)
Most commonly specified on high
temperature SERV-RITE wire yarn
insulations, the Inconel braid offers a
higher operating temperature than
the series 300 stainless steel
overbraid. When this braid is
specified on SERV-RITE SERIES
350, the performance of the material
is only surpassed by metal-sheathed
cables. Consult factory for
availability on specific wire items.

Metallic Overbraids
and Wraps
Although standard SERV-RITE wire
products are designed to yield a
high degree of abrasion resistance,
it is sometimes necessary to add an
additional metallic covering to
further enhance this property. The
following are the available
overbraids and wraps.

Tinned Copper Wire Overbraid (C)
When there is a possibility of electrical interference in the area of the
thermocouple installation, it may be
necessary to shield the wire from
electrical “noise.” Several of our
standard products use aluminized
tapes as an intrinsic shield.
However, when shielding is needed
on other constructions, a tinned
copper shield can be specified on
special order.
Stainless Steel Spiral Wrap (W)
Certain constructions are available
with a spirally applied stainless steel
wrap. The wrap yields a tough
mechanical coating that survives
well in most outdoor applications.
Consult factory for the availability on
specific catalog items. To add a
metallic overbraid or wrap, insert the
letter designator as follows:

Metals Corporation.

The SERIES 157 is an improved
version of SERIES 155. The SERIES
157 uses tape over the conductors
to improve moisture resistance.
The SERIES 157 conductors are first
wrapped with a TFE tape, braided
with fiberglass, and then
impregnated with a resin. The
insulated single conductors are then
laid parallel and braided with
SERV TEX yarn. The final coat is a
resin impregnation.

Both the SERIES 301 and 365 use
vitreous silica yarn as the insulation
on both the conductors and duplex.
This yarn retains its flexibility after
exposure to high temperatures.
The vitreous silica yarn’s greater
purity performs better at high
temperatures than other fibrous glass
products. Testing has indicated that
“contamination” will compromise this
material’s upper use temperature. For
this reason, our standard offering is
supplied without color coding or
impregnations. The 365 construction
is a cost-effective, medium insulation
build of the popular heavy duty 301
construction.
For higher temperatures consider
SERIES 350 (see page 191).

SERIES 305 is specifically
constructed for light duty
applications where size is a critical
factor. The single conductors are
insulated using a specialized yarn
wrapped on the conductors in layers.
This yarn is then impregnated to add
abrasion resistance and enhance
electrical properties. The insulated
single conductors are then laid
parallel and covered with a layer of
braided glass. A final impregnation is
applied to the braid.
For higher temperature applications,
use SERIES 321 (see page 190).

The SERIES 314 is an economical
construction for general, high
temperature applications. The
braided high temperature yarn is
applied in a unique manner that
allows SERIES 314 to be
competitively priced with other
fiberglass constructions. It produces
a finished wire that performs at
temperatures to 870°C (1600°F).
The conductors are insulated with
braided high strength fiberglass and
impregnated to improve abrasion
resistance. The impregnation is tinted
to impart color coding to primary
insulations. The insulated single
conductors are then twisted together
to yield a construction flexible
enough for most any application.

The addition of color coding and impregnation to the high temperature
fiberglass make this the logical next
step for systems which have exceeded the temperature capabilities of
standard glass insulated series.
Each conductor is covered with a
color coded, high temperature
fiberglass braid. This braid is then
impregnated to enhance abrasion
resistance and reduce fraying. The
insulated conductors are laid parallel
and covered with another braid of
high temperature fiberglass and
impregnation.

The SERIES 350 uses the ultimate
high-temperature flexible insulating
system. The ceramic fiber yarn’s
upper temperature limit often exceeds
the melting point of the material it’s
insulating. When an application
requires flexible insulation, while
pushing Type K or Type N to their
extreme limits, ceramic fiber
insulation is the only choice.
Watlow supplies standard SERIES
350 without color coding or
impregnations.* This minimizes
contaminating the pure ceramic fiber
yarn. Laboratory testing indicates the
impregnation can decrease the
upper use temperature by as much as
540°C (1000°F).
The 355 construction is a costeffective, medium insulation build of
the popular 350 heavy duty
construction.
If application temperatures exceed
SERIES 350 construction, specify
XACTPAK mineral-insulated,
metal-sheathed cable.

The SERIES 505 is the most
economical wire produced. Unlike
some competitive “ripcord” type
constructions which use only a stripe
to establish polarity, SERIES 505
single conductors are fully color
coded. The conductors are individually insulated with the proper colored PVC and fused into “ripcord” using
a proprietary process.
The insulated conductors can be
easily separated by hand once the
bond between conductors has been
slit. As with other PVC insulated
products, SERIES 505 lends itself
well to both manual and mechanical
stripping methods.

The SERIES 506 is the smallest
standard insulated wire construction.
The thin FEP wall on both primary
and duplex insulation yields a
construction that can operate safely
at temperatures far beyond common
PVC and nylon insulations.
The SERIES 506 is fully color coded
for ease of installation. Its small size
allows use in high density circuits.
Response time is minimized by small
diameter conductors. SERIES 506 is
available only in gauge sizes of #26
and smaller. For gauge sizes larger
than #26 specify SERIES 507 (see
page 196).

The SERIES 507 is the most
economical fluoroplastic insulated
wire. SERIES 507 is also available as
UL listed PLTC. Individual conductors are coated with a layer of
color coded FEP. The insulated conductors are then parallel duplexed
with an additional layer of color
coded FEP. The finished
construction has a temperature
rating of 260°C (500°F). Abrasion,
moisture and chemical resistance
are far in excess of most other
insulations.
This construction is widely used
when pulling long lengths of wire
through conduit. FEP’s low friction
coefficient and abrasion resistance
make it ideally suited for these
applications.
For higher abrasion resistance
consider Tefzel insulated
constructions, the SERIES 514.
For higher temperatures specify
SERIES 508 (see page 198).

The primary and duplex insulation
of SERIES 508 is fused TFE tape. The
tape is spirally applied to the conductor and heated. This process,
called sintering, forms the tape into a
homogeneous layer. When sintered,
the tape exhibits all of the advantages of extruded TFE insulation, while
eliminating the concentricity problems
associated with TFE extrusions.
The SERIES 508 is fully color coded
and capable of continuous operation
in excess of 260°C (500°F). Because
the fusing process causes the
duplex tape to fuse with the primary
insulation, SERIES 508 is not
recommended for applications
where it’s necessary to remove the
outer tape while leaving the primary
insulation intact.

The SERIES 509 was developed
especially for use with microprocessor
based systems. SERIES 509 (see
page 200) is also available as UL listed
PLTC .

Note: Bolded products are stocked and shipped in 100, 250, 500 and 1000 foot spools.

The conductors are insulated with
color coded FEP. They are then
twisted with a copper drain wire. An
aluminized polyester tape is
wrapped around the conductors and
drain wire. Finally, FEP is applied.
The finished construction can withstand temperatures in excess of
204°C (400°F). Twisted conductors
minimize EMI and the taped shield
eliminates most problems associated
with AC “noise.”

The SERIES 509 UL is one of a family
of constructions developed especially
for use with microprocessor based
systems. SERIES 509 UL has UL
listings for Power Limited Tray Cable
(PLTC) applications.
The conductors are first insulated with
color coded FEP. The conductors are
then twisted with a copper drain wire.
An aluminized polyester tape is wrapped around the two conductors and
drain wire. Finally, an FEP layer is
applied over the taped conductors.
The finished construction can withstand temperatures in excess of
204°C (400°F). The twisted
conductors minimizes electromagnetic
interference and the taped shield
eliminates most problems associated
with AC “noise” in the sensing circuit.

SERIES 511 is the most economical
polyimide taped construction. The
polyimide film applied to the
conductors is considered to be the
ultimate “soft” insulation. The tape
maintains its strength at temperatures
to 315°C (600°F). The FEP laminate
serves as a moisture barrier and
allows the tape to fused with itself.
The finished construction will not
unravel when cut.
The SERIES 511 conductors are
wrapped with the polyimide tape
which is fused to itself. Each
conductor is color coded with a
colored thread under the tape. The
final operation is twisting the insulated conductors into a duplex
construction, thereby eliminating the
overall duplex insulation and
minimizing cost.

The SERIES 512 is a heavier duty
version of SERIES 511 construction,
using the same polyimide insulation.
Color coding is accomplished using
the same colored thread “tracers.”
However, the SERIES 512 has a
duplex insulation of polyimide tape.
The extra wall of tape yields a
construction with increased
abrasion resistance.
For higher temperature
requirements, choose one of our
fiberglass insulated wires.
For improved abrasion resistance,
and easier color identification of
conductors, specify SERIES 513
(see page 205) when consulting the
factory.

The SERIES 513 is the ultimate
polyimide insulated wire. The multiple
polyimide tape layers along with fully
color coded conductors make this
insulation system the choice for high
reliability circuits. Abrasion, moisture
and chemical resistance are all
enhanced by additional layers of
tape and application of polyimide
varnish.
The actual construction consists of
a double polyimide tape layer
applied to each conductor. The tape
is fused by heating. Each insulated
single conductor is then coated to
impart the proper color code. Finally,
the insulated conductors are laid
parallel and covered by a double,
heat fused layer of polyimide tape.
When applications require higher
heat resistance, it is necessary to
specify fiberglass insulation.

A relatively new fluoroplastic, PFA, is
the insulation on SERIES 516. PFA’s
temperature rating is only slightly less
than TFE. However, PFA can be
applied using conventional extrusion
techniques. This produces a smooth
finish, as opposed to the spiral usually
associated with TFE tape constructions. This is important in the
food industry where taped
constructions present cleaning
problems. The smooth surface also
allows this construction to be pulled
through conduits and cut-outs more
easily.
Once each conductor has been
coated with a color coded PFA layer,
they are laid parallel and again
coated with PFA.

SERIES 900 UL is our family of
multi-pair cables for UL PLTC
applications. Standard SERIES 900
UL cables of different pair counts in
most calibrations can be shipped
quickly.
SERIES 900 UL and 900 cable starts
by insulating conductors with 105°C
(220°F) PVC. For identification, one
conductor of each pair is numbered
and twisted with its counterpart.
These “twisted pairs” are cabled with
an additional insulated copper wire
for communication use. The entire
cable is wrapped with clear
polyester tape to minimize the
chance of short circuits to the
cable’s shield. An aluminized
polyester tape shield is then spirally
applied. A copper drain wire and
heavy ripcord are longitudinally
applied under the final jacket of color
coded PVC.

SERIES 1000 UL is our family of
individually shielded and isolated
multipair cables* for UL PLTC
applications. SERIES 1000 is the non
UL equivalent. SERIES 1000 UL
cables are made by insulating
conductors with 105°C (220°F) PVC.
For identification, one conductor of
each pair is numbered and twisted
with its counterpart. The pairs are
then spirally wrapped with an
aluminized polyester tape and drain
wire to isolate them in the cable. This
eliminates “noise” that can exist in a
circuit. Individual pairs are then
cabled with an additional insulated
copper wire for communication use.
These cables are ideal for data
signals.
