methods of temperature measurement and control have been developed over
the years. Industrial process control usually requires that the temperature
sensing device must
be remote from the measuring or controlling instrument. Of the various
thermal sensing devices, the thermocouple is most commonly used, offering
the best compromise of cost,
accuracy and reliability.
We are a leading manufacturer of thermocouples. Our modern production
facilities and years of experience allow us to provide the highest quality
sensors at competitive prices.
- Element: Two wires
of dissimilar alloys joined at the tip. When the ends are exposed to
a temperature gradient, and electromotive force (EMF) is generated.
The EMF is very small, amounting to microvolts per degree.
- Protection Tube:
A metal or ceramic tube, usually closed at the end, that protects the
element from the environment of the process.
- Head or Cold End
Termination: The head is a terminal block/protective enclosure assembly
provided for connection to thermocouple extension wire. In lieu of this,
an integrated extension assembly may be provided.
- Extension Wire:
Although not a portion of the thermocouple assembly itself, the extension
wire is a critical part of the total circuit. The wire must be manufactured
from alloys compatible with the element.
