Infrared measuring height sensor

Height sensors measure the height measuring infrared light curtain consists of a light emitter and a receiver components, light emitted from the light emitter to direct the light receiving device; measuring light curtain when an object passes through the area, according to the infrared can not pass through opaque objects, the use of modulated light Scan through the infrared receiver sensitivity to light changes, reflecting the outer contour of the object, the use of serial communications hardware, to achieve control of the hardware, data processing and other functions to draw contours. Practice has proved that this method has better accuracy and real-time test results simple and intuitive. Measuring light curtain products mainly include: a light emitter, one receiver, two cable lines; measuring light curtains are made invisible infrared light-emitting light-emitting device, the receiver receives, forming a section of invisible infrared light, how much light how many points there are infrared beam on the radio, and the distance of each beam line with another beam axis spacing between the lines is, the smaller the optical axis pitch, the more dense beam line; the higher the precision; detected object through the light curtain, they will block the beam, so that the presence or absence of the block which beams converted into an electrical signal to the control and execution systems measuring light curtain output: pulse signal, analog signals, RS485 signal switch the amount of signal due to space limitations can inquire us, we are manufacturers of infrared light curtain
