How to measure the width measuring photoelectric

A measuring light curtains measuring light curtains 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, form a section not visible infrared, how many there are that many pieces of spot beam of infrared light beams and the distance between each beam line and the other is between the optical axis of the beam line spacing, optical axis pitch is smaller, more dense beam line; precision on The higher; when the object to be detected by 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 enforcement system, the electrical signal output NPN or PNP output, usually When an object through the light curtain to the control system when a level signal; analog; occlusion highest point to an object or a maximum lowest point signal output current (voltage) value, you can give a total light points blocking current (voltage) value ; RS485 / 232 serial output: given the state of the object blocking the beam for each point, is the whole point of reference MODBUS protocol; optical axis pitch: 1.25mm, 2.5mm, 5mm, 10mm, effective detection width: 70mm-3500mm Installation measured width: at installed on the bottom of the workpiece, used in strip industry, measure its width is controlled by the presence or absence of light leakage, or how much light leakage, to determine whether the product is qualified, mainly used in hole testing industry, to determine the position of an object by measuring the width of the track , mainly used in fabric and web industry, by the width of the object to determine whether the deviation, leaving the edges aligned; so a variety of industrial applications, is a measure of the light curtain old sea any manufacturer, we can make the measurement program for you.
