Copper Constantan Thermocouple Experiment

The type t has excellent repeatability between 380f to 392f 200c to 200c.

Copper constantan thermocouple experiment.

Uses tend to be restricted to ac circuits. The type t is a very stable thermocouple and is often used in extremely low temperature applications such as cryogenics or ultra low freezers. It is found in other laboratory environments as well. Calibrating calibration charts of thermocouple.

Constantan is also the negative element of the type j thermocouple with iron being the positive. Also it is the negative element of the type t thermocouple with ofhc copper the positive.

A device such as that shown above can be produced with many junctions which when connected in series gives output voltages of the order of one volt rather than the usual microvolts encountered with copper constantan thermocouples. Type k thermocouple consisting of chromel and alumel alloys it is also used in. Type t thermocouples are used at cryogenic temperatures.
