The photoelectric hot water supply systems, based on DC/DC converter SOLAR KERBEROS, may finely be adjusted, as well as you can receive the important information about operation of system on the colored touch-screen. Alibaba.com offers 934 photoelectric water sensor products. About 36% of these are sensors, 1% are alarm. A wide variety of photoelectric water sensor options are available to you, such as level sensor, position sensor. This is a photoelectric water liquid level sensor that is operates using optical principles. The advantages of this are good sensitivity and no need for mechanical parts - meaning less calibration! The corrosion resistant probe is easily mounted and can handle high temperature and high pressure. Einstein and Millikan described the photoelectric effect using a formula (in contemporary notation) that relates the maximum kinetic energy (K max) of the photoelectrons to the frequency of the absorbed photons (f) and the threshold frequency (f 0) of the photoemissive surface. Photoelectric sensors are made up of a light source (LED), a receiver (phototransistor), a signal converter, and an amplifier. The phototransistor analyzes incoming light, verifies that it is from the LED, and appropriately triggers an output. The photoelectric effect is the emission of electrons or other free carriers when light hits a material. Electrons emitted in this manner can be called photoelectrons. This phenomenon is commonly studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry or electrochemistry.
