DESCRIPTION:
Mineral insulated thermocouple consists of two dissimilar
thermocouple wires that are insulated using highly compressed ceramic powder and
encased in a metallic sheath. Due to its inherent features such as flexibility
MI thermocouple cable can be used in a wide variety of otherwise difficult
temperature measuring applications. Compared with the conventional thermocouples, MI thermocouple have many advantages.
BASIC THERMOCOUPLE THEORY
|
A thermocouple is a closed
loop circuit that consists of two dissimilar metal wires welded together
at both ends.
|
|
When a temperature
difference exists between the two junctions, an electromotive force
(thermal emf) develops and a thermoelectric current flows in the circuit.
|
|
The emf and its polarity
depends on the temperature difference and the combinations of the two
metal wires, and are not affected by the size or length of the wires. |
|
When the relationship
between the temperature difference and the thermal emf induced within is
known beforehand for a particular thermocouple, temperature can be
measured. |
