German Vaisala sensors, Vaisala models, Vaisala prices

Vaisala sensors generally consist of 2 parts: the processing path and the processing elements. Their basic principle is based on the photoelectric effect, converting changes in the measured quantity into changes in optical signals, and then further converting non-electrical signals into electrical signals via photoelectric components. The photoelectric effect refers to illuminating an object with light, which can be viewed as a stream of photons with specific energy bombarding the object. At this point, photon energy is transferred to electrons, with the entire energy of one photon being absorbed by one electron at once. After receiving the energy from the photon, the state of the electron
