  • Resistance temperature sensor
    Patent number: 4139833
    Abstract: A polished ceramic substrate is provided with an insulation layer of silicon monoxide (SiO), over which a nickel metal thin-film is laid down in a spiral or serpentine pattern, taking up a desirably small area, but at the same time giving a high electrical resistance. Finally, a cover or protective layer of silicon monoxide is then deposited over the resistor, serving to protect it from the possibility of outside contamination.
