How
to choose your Thermocouple
| Tip
shape |
Fine
Thermocouple |
The
fine Thermocouple tip is ideally suited to temperature
measurement of very small components, with a fast response
time and high accuracy. The bare wire thermocouple tip can be fixed using an
Ag paste. This type of Thermocouple is recommended as an OEM product
not as a reusable Thermocouple. The Standard tip diameter is 25
micron, with a 13 micron diameter tip for special applications. |
| Sheet
Thermocouple |
The
sheet Thermocouple is designed to measure surface temperature.
They can also offer high strength, high accuracy and a fast response
time. We would recommend using single sided, black body Thermocoulpes with capton
tape to secure the Thermocouple as this will absorb the
Infra-red energy. photo
|
| Fine
and Sheet Thermocouple |
Rolling
milled fine Thermocouples, 25 or 50 micron.
The
25 micron diameter tip wire is roll milled to 10 micron thick,
and the 50 micron diameter tip wire is roll milled to 20 micron
thick.
Very fast response and high accuracy.
Recommended for applications such as silicon wafer. |
| Multi
purpose Thermocouple |
Available with 100 or 200 micron wire, these Thermocouples have a wire
shaped tip not a ball as used in some Thermocouples. This
gives a faster response time and greater accuracy. This
is a very robust Thermocouple. Multi purpose Thermocouples are recommended for applications
where the temperature is not changing rapidly. The Thermocouple
tip can be fixed using solder or ceramic bonding into or
onto
the substrate being measured.
|
Insulation |
Glass |
Glass
insulation will operate at a constant temperature not
exceeding 250°C temperatures up to 300°C would
be acceptable only for short periods of time. Glass insulation
is very flexible, however, it may not be suited to clean
room applications. Detail |
Teflon |
Maximum
operating temperature for Teflon is 200°C we would
recommend Teflon for measuring the temperature of liquids,
chemicals, and any application where it would be open
to the elements. Detail |
Ceramic |
Suitable for applications where high temperatures are
likely, for example ovens, furnaces, rocket / jet engine
exhaust ports etc. However this material would not be
suitable for any applications involving water, as the
ceramic bond would
dissolve in water Detail
|
Insulated
wire diameter. |
200 micron |
200 micron wire would be used if mechanical strength is a
concern and would be recommended for any application where
the cable would be longer than 2 meters, to minimise
interference by external electromagnetic interference. Detail |
100 micron |
100 micron wire would have very
good properties for bending around a small radius. However;
it would be more susceptible to external interference
from any electromagnetic waves. Not recommended for cable
lengths exceeding 2 metres. Detail
|
Option |
Solder
coat Tip |
This
type of bare wire Thermocouple is easy to attach in applications
where a solder joint is possible. |
One

Sheet
Thermocouples can be attached to the substrate by capton
tape, we recommend our patented one sided black body Thermocouples. The black body can absorb the
infra-red energy resulting in a faster response time.

| Insulation
on bare wire & tip |
Can
be used to measure the surface temperature where a low
voltage may be present. The insulated wire and tip can
also protect the Thermocouple in corrosive liquids and harsh
environments. The insulated wire will ensure that you are
measuring the temperature at the tip and not along the
wire length. Detail
The
operating temperature for the insulation is 300°C. The insulation is applied in three seperate coats to prevent
pin holes, however, this will increase the diameter as
follows: 200 micron will increase to 210 micron, 25 micron
to 28 micron, and 50 micron increases to 56 micron. |
Insulation
on bare wire only (not on tip) |
For
applications where the bare wire could cause a short circuit,
for example, if you are attaching the Thermocouple tip
with solder, we would recommend this option. |

Bare

10 mm, however it is possible to manufacture to your specific
request between 5 mm & 23 mm without charge. But please
take care, the longer the wire the more difficult it is
to use. |

Please Note: Heat Resistance of Ceramic insulation is approximately
1000°C. However, 320 micron diameter wire will protrude
from ceramic insulation, at a temperature of 600°C due to CTE (coefficient of thermal expansion) mismatch between
almel and chromel. We would therefore recommend that you choose
200 micron diameter wire, enabling measurement of higher temperatures.
Although
we maintain strict quality control, during the manufacture
of our products, some of the dimensions listed may vary.
