What is a Thermocouple Thermometer? Construction & How it ...

2009-02-20· Thermocouple is a temperature sensor composed of two metals that generate emfs (electromotive forces) or voltages when there are temperature differences between them. The amount of voltage produced is dependant on these differences. Thermocouples operate by exploiting the Seebeck effect. Thermocouples are popular temperature sensors found in places as diverse as hospitals, thermometers ...
