Pressure sensor having a resistor element on a glass layer with electrodes connected thereto |
摘要 |
A pressure sensor including a plate-shaped metal substrate; a glass layer provided on a surface of the metal substrate and mainly containing a partially devitrified enamel composition; a resistor element which is provided on a surface of the glass layer and has an electric resistance changed in accordance with the degree of strain thereof; and a pair of electrodes connected to the resistor element. The resistor element is provided so as to receive a stress, a pressure, or a load applied perpendicularly to a surface thereof. Alternatively, both surfaces of the metal substrate are provided with glass layers, respectively, and the resistor element is provided on one of the glass layers.
