Operation Theory of Thermocouple

 

The working principle of the thermocouple is based on the physical phenomenon that two conductors with different components are connected into a loop. If the temperature of the two terminals is different, heat flow will be generated in the circuit.

Thermal Response Time

 

When step change of temperature happens, τ0.5 is used to indicate the time for current output signal of instrument changes into 50% of the step change value.







Wire Selection

 

The compensation wire shall match with the graduation of thermocouple. Compensation wires of different cross-section area or types shall be selected depending on distance, ambient temperature, and demands on protection.







Generally, copper conductor shall be adopted for connection wire of thermal resistance. Cross-section area of the wire to be selected depends on distance, and insulation materials and different protections of the wire to be selected depend on environment conditions.
