Platinum
Useable in oxidizing. reducing or inert atmospheres as well as vacuum. Not

Recommended for continuously oxidizing or inert atmospheres. Sub-zero limits
of error are not established. Highest thermoelectric output of common
calibrations.
Recommended for high temperature. Must be protected with a non-metallic
protection tube and ceramic insulators. Continued high temperature usages
cause grain which can lead to mechanical failure. Negative calibration drift
causedby rhodium diffusion to pure leg as well as from rhodium volatilization.
Type R is generally used in industry while Type S is general used in laboratories.

Very high temperature applications in inert or vacuum atmospheres. Preferred
over Tungsten/26% Tungsten Rhenium because it is less brittle at low
temperatures.
The ductility of W3R3 leg is superior to pure Tugnsten, but not as good as W5Re.
This combination has the highest output if the 3 common Tungsten Rhenium
calibrations from 1860 to 4200°F.
Can be used in applications where Type K elements have shorter life and stability
problems due to oxidation and the developement of "green rot".

Lead wire is stranded, silver plated copper with teflon insulation for low range units, and stranded,
silver plated copper with fiberglass insulation for high range units. Three lead wires are
recommended to compensate for lead wire resistance in industrial applications.
Leadwire Insulation

WIRE CONFIGURATIONS
Two-Wire
Provides one connection to each end of the element. This construction is suitable where the
resistance of the lead wire may be considered as an additive constant in the circuit, and particularly
where the changes in lead resistance due to ambient temperature changes may be ignored.
Three-Wire
Provides one connection to one end of the element and two to the other end of the element.
Connected to an instrument designed to accept three wire input, sufficient compensation is usually
achieved for leadwire resistance and temperature change in leadwire resistance. This is the most
commonly used configuration.
Four-Wire
Provides two connections to each end of the element to completely compensate for leadwire
resistance and temperature changes in the leadwire. This configuration is used where highly accurate
temperature measurement is vital.

THERMOCOUPLE SELECTION
Selecting the proper thermocouple and installing it correctly with provide you
with more accurate results and give the devise a longer life time. The following are
some helpful tips for selecting and maintaining thermocouples.
A. Thermocouples should be protected.
Many external factors can affect the composition of the thermocouple
materials causing skewed readings and shortened lifetime. Evaporation, oxidation,
contamination, corrosion, diffusion, and induced EMF must all be considered when a
thermocouple is being put into service. Protective sheaths can be used in the
construction to protect the device. If the thermocouple contains a bare wire, it is
important that the protection tubes are clean and have the proper diameter and
length to allow proper ventilation inside.
B. Select practical and large wire.
Wire that contains heavier wire is often more stable in a high temperature
environment when compared with a lighter gauge. However, fine gauge wire
provides rapid response and flexibility. A compromise must be made using these
factors to determine the largest wire possible to meet the specifications.
C. Select proper location for installation.
Thermocouple must be installed in an area that properly represents the
temperature of the equipment or substance that is being measured.
D. Ensure proper thermocouple depth.
Since heat can be transferred away from the thermocouple sensor, it is
important to ensure the thermocouple has sufficient depth to gain an accurate
reading.
E. Maintain a constant immersion depth.
Imperfections in the thermocouple wires can result from factors such as
oxidation, corrosion, and evaporation. These imperfections can cause inaccurate
readings if the depth of the thermocouple is altered.
F. Heating cycles can affect accuracy.
It is recommended that the thermocouples be used at a single temperature or
increasingly higher temperatures to maintain high accuracy. However, this is not
always the case. It must be accounted for that there will be some error when cyclic
heating occurs. The error can be reduced by using thermocouples which are still in
good condition.
G. Check equipment regularly.
It is important to check and repair the thermocouples, protection tubes, and
extension wires for any damage. Checks should occur as frequent as necessary,
however, once a month is usually sufficient. Check to see if the protection tubes are
burnt out or damaged to prevent harm to the thermocouple. Check thermocouples
in place if possible. If not, they should be reinserted to at least the same depth to
avoid error. Make sure the external wire reaches the resistance equipment.

TROUBLE-SHOOTING
If a thermocouple is giving erroneous readings, the following steps should be taken
to spot the error.
A. Check Circuit
Check the polarity of the thermocouple at each connection. They can often
be identified by magnetism or colour coding. The negative thermocouple wire should
connect to the negative extension wire, and in turn, to the negative side of the
meter. This should also be true for the positive connections.
B. Check Instrumentation
After checking the circuit, turn your attention to control meter or recording
instrument. Make sure the instrument in set to the proper thermocouple type.
Check the room temperature setting (cold junction compensation). Do this by
removing the extension wires and placing a jumper wire across the meter connection
terminals. The reading should coincide with the room temperature. If problems still
arise, compare the reading of a test thermocouple with known accuracy (also
connected to a meter of known accuracy) with the thermocouple in question. Make
sure the test thermocouple is placed as close to the original as possible to ensure
they are measuring the same temperature.
C. Check Thermocouple
Thermocouples are always susceptible to a change in composition which could
cause faulty readings. This could be due to many factors such are oxidation,
corrosion, or contamination that often c ome from such things as brazing alloys and
fluxes. Check the working thermocouple by hooking it up to a test meter of known
accuracy. If the working meter reading is the same as the previous test reading of
known accuracy, then the working thermocouple is not the problem.
D. Test Meter and Extension Wires
Connect the extension wires to a test thermocouple of known accuracy and
observe the reading. If the reading is different than obtained with the test meter,
then the fault lays in either the working meter or extension wires.
Checking all of these components of the system can often result in diagnosing the
problem and finding a solution. If the error is directly due to a faulty thermocouple,
then it should be removed and inspected. If the thermocouple is severely corroded
or oxidized then it should be replaced. It is often better to replace an inaccurate
thermocouple than to risk a loss or product or time due to temperature problems.

CAUSES OF AGING (DRIFT)
Aging refers to a positive EMF shift (more output) of nickel thermocouple
alloys resulting from a temperature gradient along the thermocouple elements. The
temperature that aging occurs is estimated to be around 370° to 540°C (700° to
1000°F). There are a few things that can increase the amount of EMF shift:
- The temperature that is being measured or the previous thermal history of
the thermocouple.
- The thermocouple composition.
- Duration of aging temperature.
- Amount of thermocouple exposed to the aging temperatures.
It must be recognized that aging depends on the application for which the
thermocouple is being used and the temperature gradient it experiences. The
operating temperature of the thermocouple should be checked. If the thermocouple
has never been exposed to aging temperatures, it should never have errors due to
aging.
To reduce the inaccuracy of reading temperatures in the aging range, a preaged thermocouple may be used. Pre-aged thermocouples are heat treated and
have special compositions to minimize errors caused by aging. However, if these are
heated above the aging range then the effect of the pre-aging can be removed. For
applications where the temperature is above the aging range, it is important to keep
as little length of thermocouple as possible in the aging range. This will help to
minimize the aging effects.
The effects of the aging process can actually be removed. This is done by
heating the entire thermocouple above 870°C (1600°F) for at least 5 minutes. Then
the thermocouple should be rapidly cooled to below the aging temperatures. This
should restore the wire to its original calibration.

HOT OR MEASURING JUNCTIONS
Ungrounded Junction (U)
The welded thermocouple junction is fully isolated from the welded closure of the sheath. This
junction provides electrical isolation to reduce problems associated with electrical interference.
Ungrounded junctions are also recommended for use in extreme positive or negative temperatures,
rapid thermal cycling and for ultimate corrosion resistance of the sheath alloy. All ungrounded
junctions exceed 100 megaohms resistance @ 100V dc at ambient room temperatures.
Exposed Junction (E)
The thermocouple wires are welded and exposed. The insulation is not sealed against liquid or gas
penetration. Recommended where fast response is desired, and corrosive conditions are nonexistent.
The exposed hot junction length for 1/8-inch diameter sheaths and above is typically equal to the
outside diameter of the sheath. The exposed junctions for sheath diameters less than 1/8-inch
diameter are supplied as sheilded junctions.
Grounded Junction (G)
The thermocouple junction is welded securely into the closure end of the sheath, becoming an integral
part of the weld. This is a good general purpose, low cost junction providing faster response times
than an un-grounded junction of similar sheath diameter. Grounded junctions should not be used with
Type T thermocouples, due to the copper wire.

Isolab's Resistance Temperature Detector's are available in the same styles as our thermocouples are.
Standard accuracy is 0.3%, but are available in 0.01% for more accuracy. Standard temperature RTD's
are designed and built to be moisture resistant, where as high temperature RTD's generally are not.
Isolab's RTD's are built with a 316SS sheath as standard.

CSA FILE #217989
Explosion Proof Fixed Element Thermocouples are for use in U.S. and Canadian hazardous
areas. They are designed to extinguish flames inside the device eliminating the potential for
ignition of . ammable mixtures in the surrounding atmosphere. FM and CSA approved
assemblies, dependant on connection head type, meet XP Class I, Division 1, Group A, B, C
and D; DIP Class II, Division I, Groups E, F, G and Class III, Division 1. They may be
installed directly in the process without being inserted into a thermowell. The assemblies
feature 316 stainless steel sheaths in various diameter sizes and ungrounded isolated
junctions. They are available with or without process mountings and with aluminum or
stainless steel explosion proof connection heads.

Class III
Locations that are hazardous
because of the presence of easily
ignitable fibers or flyings are not
likely to be in suspension in the air
in quantities sufficient to produce
ignitable mixtures.
DIVISIONS
1
2
Locations where hazardous material exists
under normal operating conditions or
through breakdown or repair.
Locations where hazardous materials are
expected to be confined within closed
containers of closed systems but may
become present through a leak or process
failure.
Combustible dust is in the air under normal
operating conditions in quantities sufficient
to produce explosive or ignitable mixtures
or through breakdown or repair.
Combustible dust may be in the air in
sufficient quantities to produce an
explosion due to abnormal operations or
failure of electrical equipment.
Easily ignitable fibers or material producing
combustible flyings are handled,
manufactured or used.
Easily ignitable fibers are stored or handled
other than in the process of manufacture.
Examples

There are no defined groups.
Examples are Textiles,
Woodworking, Paper Fibers.
METHODS OF PROTECTION
Explosion Proof (XP)
Class I, Division 1, 2
Apparatus enclosed in a case that is
capable of withstanding an explosion of
a specified gas or vapour that may
occur within it and of preventing the
ignition of a specified gas or vapour
within, and that operates at such an
external temperature that a
surrounding flammable atmosphere will
not be ignited therby.
091
Dust-Ignitable (DIP)
Class II, Division 1, 2
Equipment enclosed in a manner that
excludes dust and does not permit arcs,
sparks or heat otherwise generated or
liberated inside of the enclosure to
cause ignition of exterior accumulations
or atmospheric suspensions of a
external temperature that a specified
dust on or in the vicinity of the
enclosure.
Dust-Ignitable (DIP)
Class II, Division 1, 2
Class II, Division 1, 2
Class III, Division 1, 2
Equipment not capable of releasing
sufficient electrical or thermal energy
under normal conditions to cause
ignition of a specific flammable or
combustable atmospheric mixture it its
most easliy ignitable concentration.
Nonincendive (NI)
Class II, Division 2
Class II, Division 2
Class III, Division 1, 2
Equipment having electrical circuitry
that is incapable, under normal
operating conditions, of causing ignition
of a specified flammable gas-air,
ignition of a specified gas or vapour
vapour-air or dust-air mixture due to
arcing or thermal means.

THERMOCOUPLE ASSEMBLIES WITH
PRESSURE TIGHT WELLS
Thermocouples with thermowell's are designed for applications where the thermocouple itself
is not able to stand up to the media being measured. They are also designed to be used in
applications where the media being measures is under alot of pressure or where the application
does not permit the removal of the thermocouple without draining the contents of such things
as tanks or vessels.

Platinum
Useable in oxidizing. reducing or inert atmospheres as well as vacuum. Not
subject to corrosion in moist atmospheres. Limits are published for sub-zero
temperature ranges.
Recommended for continuously oxidizing or inert atmospheres. Sub-zero limits
of error are not established. Highest thermoelectric output of common
calibrations.
Recommended for high temperature. Must be protected with a non-metallic
protection tube and ceramic insulators. Continued high temperature usages
cause grain which can lead to mechanical failure. Negative calibration drift
causedby rhodium diffusion to pure leg as well as from rhodium volatilization.
Type R is generally used in industry while Type S is general used in laboratories.

Similar to type R & S but output is lower. Also less susceptible to grain growth
and drift.

Very high temperature applications in inert or vacuum atmospheres. Preferred
over Tungsten/26% Tungsten Rhenium because it is less brittle at low
temperatures.
The ductility of W3R3 leg is superior to pure Tugnsten, but not as good as W5Re.
This combination has the highest output if the 3 common Tungsten Rhenium
calibrations from 1860 to 4200°F.
Can be used in applications where Type K elements have shorter life and stability
problems due to oxidation and the developement of "green rot".

THERMOCOUPLE SELECTION
Selecting the proper thermocouple and installing it correctly with provide you
with more accurate results and give the devise a longer life time. The following are
some helpful tips for selecting and maintaining thermocouples.
A. Thermocouples should be protected.
Many external factors can affect the composition of the thermocouple
materials causing skewed readings and shortened lifetime. Evaporation, oxidation,
contamination, corrosion, diffusion, and induced EMF must all be considered when a
thermocouple is being put into service. Protective sheaths can be used in the
construction to protect the device. If the thermocouple contains a bare wire, it is
important that the protection tubes are clean and have the proper diameter and
length to allow proper ventilation inside.
B. Select practical and large wire.
Wire that contains heavier wire is often more stable in a high temperature
environment when compared with a lighter gauge. However, fine gauge wire
provides rapid response and flexibility. A compromise must be made using these
factors to determine the largest wire possible to meet the specifications.
C. Select proper location for installation.
Thermocouple must be installed in an area that properly represents the
temperature of the equipment or substance that is being measured.
D. Ensure proper thermocouple depth.
Since heat can be transferred away from the thermocouple sensor, it is
important to ensure the thermocouple has sufficient depth to gain an accurate
reading.
E. Maintain a constant immersion depth.
Imperfections in the thermocouple wires can result from factors such as
oxidation, corrosion, and evaporation. These imperfections can cause inaccurate
readings if the depth of the thermocouple is altered.
F. Heating cycles can affect accuracy.
It is recommended that the thermocouples be used at a single temperature or
increasingly higher temperatures to maintain high accuracy. However, this is not
always the case. It must be accounted for that there will be some error when cyclic
heating occurs. The error can be reduced by using thermocouples which are still in
good condition.
G. Check equipment regularly.
It is important to check and repair the thermocouples, protection tubes, and
extension wires for any damage. Checks should occur as frequent as necessary,
however, once a month is usually sufficient. Check to see if the protection tubes are
burnt out or damaged to prevent harm to the thermocouple. Check thermocouples
in place if possible. If not, they should be reinserted to at least the same depth to
avoid error. Make sure the external wire reaches the resistance equipment.

TROUBLE-SHOOTING
If a thermocouple is giving erroneous readings, the following steps should be taken
to spot the error.
A. Check Circuit
Check the polarity of the thermocouple at each connection. They can often
be identified by magnetism or colour coding. The negative thermocouple wire should
connect to the negative extension wire, and in turn, to the negative side of the
meter. This should also be true for the positive connections.
B. Check Instrumentation
After checking the circuit, turn your attention to control meter or recording
instrument. Make sure the instrument in set to the proper thermocouple type.
Check the room temperature setting (cold junction compensation). Do this by
removing the extension wires and placing a jumper wire across the meter connection
terminals. The reading should coincide with the room temperature. If problems still
arise, compare the reading of a test thermocouple with known accuracy (also
connected to a meter of known accuracy) with the thermocouple in question. Make
sure the test thermocouple is placed as close to the original as possible to ensure
they are measuring the same temperature.
C. Check Thermocouple
Thermocouples are always susceptible to a change in composition which could
cause faulty readings. This could be due to many factors such are oxidation,
corrosion, or contamination that often c ome from such things as brazing alloys and
fluxes. Check the working thermocouple by hooking it up to a test meter of known
accuracy. If the working meter reading is the same as the previous test reading of
known accuracy, then the working thermocouple is not the problem.
D. Test Meter and Extension Wires
Connect the extension wires to a test thermocouple of known accuracy and
observe the reading. If the reading is different than obtained with the test meter,
then the fault lays in either the working meter or extension wires.
Checking all of these components of the system can often result in diagnosing the
problem and finding a solution. If the error is directly due to a faulty thermocouple,
then it should be removed and inspected. If the thermocouple is severely corroded
or oxidized then it should be replaced. It is often better to replace an inaccurate
thermocouple than to risk a loss or product or time due to temperature problems.

CAUSES OF AGING (DRIFT)
Aging refers to a positive EMF shift (more output) of nickel thermocouple
alloys resulting from a temperature gradient along the thermocouple elements. The
temperature that aging occurs is estimated to be around 370° to 540°C (700° to
1000°F). There are a few things that can increase the amount of EMF shift:
- The temperature that is being measured or the previous thermal history of
the thermocouple.
- The thermocouple composition.
- Duration of aging temperature.
- Amount of thermocouple exposed to the aging temperatures.
It must be recognized that aging depends on the application for which the
thermocouple is being used and the temperature gradient it experiences. The
operating temperature of the thermocouple should be checked. If the thermocouple
has never been exposed to aging temperatures, it should never have errors due to
aging.
To reduce the inaccuracy of reading temperatures in the aging range, a preaged thermocouple may be used. Pre-aged thermocouples are heat treated and
have special compositions to minimize errors caused by aging. However, if these are
heated above the aging range then the effect of the pre-aging can be removed. For
applications where the temperature is above the aging range, it is important to keep
as little length of thermocouple as possible in the aging range. This will help to
minimize the aging effects.
The effects of the aging process can actually be removed. This is done by
heating the entire thermocouple above 870°C (1600°F) for at least 5 minutes. Then
the thermocouple should be rapidly cooled to below the aging temperatures. This
should restore the wire to its original calibration.

HOT OR MEASURING JUNCTIONS
Ungrounded Junction (U)
The welded thermocouple junction is fully isolated from the welded closure of the sheath. This
junction provides electrical isolation to reduce problems associated with electrical interference.
Ungrounded junctions are also recommended for use in extreme positive or negative temperatures,
rapid thermal cycling and for ultimate corrosion resistance of the sheath alloy. All ungrounded
junctions exceed 100 megaohms resistance @ 100V dc at ambient room temperatures.
Exposed Junction (E)
The thermocouple wires are welded and exposed. The insulation is not sealed against liquid or gas
penetration. Recommended where fast response is desired, and corrosive conditions are nonexistent.
The exposed hot junction length for 1/8-inch diameter sheaths and above is typically equal to the
outside diameter of the sheath. The exposed junctions for sheath diameters less than 1/8-inch
diameter are supplied as sheilded junctions.
Grounded Junction (G)
The thermocouple junction is welded securely into the closure end of the sheath, becoming an integral
part of the weld. This is a good general purpose, low cost junction providing faster response times
than an un-grounded junction of similar sheath diameter. Grounded junctions should not be used with
Type T thermocouples, due to the copper wire.
