introduction:The principle of the action of light flux on photoelectric element:Different optical measurement and control systems made are varied,photocell(Optical measurement and control system)Output properties can be divided into two categories,Analog photoelectric sensorSum pulse(Switch)Type photoelectric sensor.Analog photoelectric sensors are to be measured for conversion The photoelectric sensor generates a continuously varying photocurrent,There is a single value relationship between it and being measured.Analog photoelectric sensor as measured(Detecting target object)The method can be divided into transmission(absorb)type,Diffuse reflection type,Blackout type(Beam stop)Three broad categories.The so-called transmission type means that the measured object is placed in the light path,The light energy emitted by the constant light source passes through the measured object,After some of it is absorbed,The transmitted light is projected onto the photoelectric element;The so-called diffuse reflection means that the li
