About this product:
Thermocouple cables are specialized types of cables used to connect
thermocouples to measuring instruments. They are designed to
maintain the integrity of the thermoelectric signal generated by
thermocouples and to ensure accurate temperature measurements. The
K, N, E, T, J, and S types refer to different thermocouple types,
each with its own characteristics, materials, and applications.
Here’s a brief overview of each type along with relevant
information about thermocouple cables:
Types of Thermocouples
Type K (Chromel-Alumel)
Composition: Chromel (nickel-chromium alloy) and Alumel
(nickel-aluminum alloy).
Temperature Range: -200°C to +1260°C (-328°F to +2300°F).
Applications: General-purpose, industrial applications, and food
processing.
Type N (Nicrosil-Nisil)
Composition: Nicrosil (nickel-chromium-silicon alloy) and Nisil
(nickel-silicon alloy).
Temperature Range: -200°C to +1300°C (-328°F to +2372°F).
Applications: High-temperature applications and environments where
oxidation is a concern.
Type E (Chromel-Constantan)
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.
