About this product:
Thermocouples are widely used temperature sensors that operate on
the principle of thermoelectricity. They consist of two dissimilar
metal wires joined at one end, where a voltage is generated that
corresponds to the temperature difference between the junction and
the other ends of the wires. Here are some key points and notes on
the use of thermocouples:
Principle of Operation
Seebeck Effect: The basic operating principle of thermocouples is
the Seebeck effect, where a voltage is generated when there is a
temperature difference between the junction (hot junction) and the
reference end (cold junction).
Voltage Output: The generated voltage is proportional to the
temperature difference, allowing for temperature measurement.
Types of Thermocouples
Common Types:
Type K (Chromel-Alumel): Wide temperature range (-200°C to 1260°C),
good for general-purpose applications.
Type J (Iron-Constantan): Limited range (-40°C to 750°C), suitable
for lower temperatures.
Type T (Copper-Constantan): Good for cryogenics and low-temperature
applications (-200°C to 350°C).
Type E (Chromel-Constantan): Good sensitivity and a range (-200°C
to 900°C).
Type N (Nicrosil-Nisil): Stable for high temperatures (up to
1300°C) and suitable for harsh environments.
What is a Thermocouple?
- A thermocouple is a type of transducer that converts thermal energy
into electrical energy. It is made by joining wires of dissimilar
metals to create a junction. When the temperature at this junction
changes, it generates a voltage that can be measured and used to
determine the temperature.
- The thermocouple operates based on the Seebeck Effect, which states
that when dissimilar metals are joined at a junction, they generate
a small, measurable voltage in response to changes in the
temperature at that junction. The magnitude of the voltage produced
depends on both the temperature change and the properties of the
metals used.
- A thermocouple is composed of two insulated wires made from
different metals, which are connected to a measuring device. It
functions as a safety and monitoring tool for various processes and
equipment, providing crucial temperature measurements and ensuring
proper operation.
- The operation of a thermocouple is illustrated in the image below.
As the temperature increases at the junction of the wires on the
left, the resulting temperature change is displayed on the gauge on
the right.
- Thermocouple assemblies are engineered for use in harsh, severe,
and demanding environments. The selection of a thermocouple depends
on factors such as the temperature range, ambient atmosphere, and
the type of media being measured. Additionally, the size and shape
of the thermocouple are tailored to the specific application,
considering factors like required accuracy and response speed.
