Thermocouple Wire and its Applications
Type T Thermocouple Wire
The Seebeck Effect, Peltier Effect and Thompson Effect
The term “thermoelectric effect” encompasses three separately identified effects: the Seebeck effect, Peltier effect, and Thomson effect. The Seebeck and Peltier effects are different manifestations of the same physical process; textbooks may refer to this process as the Peltier–Seebeck effect (the separation derives from the independent discoveries of French physicist Jean Charles Athanase Peltier and Baltic German physicist Thomas Johann Seebeck). The Thomson effect is an extension of the Peltier–Seebeck model and is credited to Scottish born Sir William Thomson, Lord Kelvin.

Medical Grade Thermocouple Wire
Medical grade thermocouple (TC or T/C Twist Wire) wires are used in treatment of tachycardia and atrial fibrillation where there is a need for measurement of tissue temperature at the ablation site. Our high quality wire provides precise and accurate measurement of delivered energy and tissue temperature during radiofrequency ablation of cardiac arrhythmias.
- Available in sizes 36 to 48 AWG
- May be made as parallel bonded or twisted wire constructions
- May have two or more legs
- Variety of film insulations including polyimide in colors red, green, black, and natural

Type | Positive Lead | Negative Lead | Comments |
---|---|---|---|
E | Nickel-Chromium | Constantan | Highest sensitivity; best for temperatures down to 40 K |
T | OFHC Copper | Constantan | Low temperature and cryogenic applications; good where moisture is present |
K | Nickel-Chromium | Nickel-Aluminum | Largest temperature range; recommended for use in inert atmosphere |
