<p>The device is a pressure sensor based on optical interference in a sensor body, with a cavity created between two parts spaced apart from each other, where the light signal is transported directly in vacuum, air, gas, liquid, another gas medium or a transparent solid material from a source of light to the sensor body and subsequently in the same media to a photo detector which outputs an electrical signal which constitutes a measurement of the pressure which is desired to measure.</p> |
