German PPM DOMET sensor PPM DOMET model PPM DOMET price

PPM DOMET sensors generally consist of 2 parts: the processing path and the processing element. Their basic principle is based on the photoelectric effect, converting changes in the measured variable into changes in optical signals, and then further converting non-electrical signals into electrical signals using 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, and the entire energy of one photon is absorbed by one electron at once. After receiving the energy transmitted by the photon, the electron's state
