41. Even a sheath of magnesium oxide insulating the thermocouple will not keep the hydrogen out. 42. Miniature thermocouples have been developed that convert body heat into electricity and generate 40RTG batteries. 43. This allowed a signal to be sent directly from a thermocouple to a recording device. 44. The SiGe thermocouples / unicouples convert this heat to hundreds of Watts of electrical power. 45. Gas furnaces with pilot lights usually have a device called a thermocouple next to the pilot. 46. This is now called the Peltier Seebeck effect and is the basis of thermocouples and thermopiles. 47. A thermocouple is a Seebeck effect. 48. Temperature is measured with a thermocouple . 49. Similarly, thermocouples use the Peltier Seebeck effect to measure the temperature difference between two points. 50. During the mid-1970s, the company introduced the industry's first thermocouple product.
