Germany WTW GMBH sensor WTW GMBH model WTW GMBH price

WTW GMBH sensor is a device that converts optical signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon where electrons in a material absorb photon energy when light irradiates certain substances, resulting in corresponding electrical effects. Based on the different manifestations of the photoelectric effect, it is classified into three categories: external photoelectric effect, internal photoelectric effect, and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and solar cells. The performance and characteristic curves of photoelectric devices are analyzed. WTW G
