A thermocouple is a bi-metallic
junction i.e. a junction between two different metals that produces voltage
related to temperature difference. Thermocouples are classified depending on
different alloys used for different temperature ranges. Some of the
thermocouple types are as ;
'K' Type : Chrome (Ni/Cr)
+ Alum (Ni/Al)
'J' Type : Iron (Fe) +
Constantan (Cu/Ni)
'T' Type : Copper (Cu) +
Constantan (Cu/Ni)
'E' Type : Chrome (Ni/Cr)
+ Constantan (Cu/Ni)
For temperature measuring
requirement, wherein measuring point is far from the measuring instrument,
intermediate connections have to be made for extending the path. For such
application conventional type terminal blocks cannot be used to create the
required extension, since current carrying parts are made of either copper
or copper alloy which are different than the thermocouple metals or alloys
as mentioned above. to overcome this problem thermocouple terminal blocks
are employed. Thermocouple terminal blocks are constructed using the same
type of metal / alloy as that of thermocouple intended for measuring
temperature. Thermocouple terminal blocks are used in pairs.
We offer
thermocouple terminal blocks in all four types of thermocouples described
above.
