Infrared light curtains, safety light curtains manufacturers Lingwei Sheng, security screens LVS-0620 prices

Lingwei Sheng (linvsen) -LVS Series safety light curtain: curtains divided into two purposes, one is security screens, one is measuring light curtain. Security screens mainly used for industrial safety, measuring light curtains suitable for detecting whether a product compliance. Light curtains Photoelectric sensors measuring principle is a change in light intensity of the received electronic device sensors, including optical systems, amplifiers and switching output device. All photoelectric sensors use modulated light to rule out the possible influence around the light source, at work, photoelectric sensors emit light, when the detected object through, depending on the detection mode, the collection of light objects or absorb light or the light reflected to the photosensor , thereby resulting in the intensity of light received by the light receiving produce changes, which changes the value of the trigger signal output to realize the detection function. Measuring light curtain is a special photoelectric sensors and conventional beam photoelectric sensors, separated from each other and comprising two parts placed opposite the optical transmitter and receive unit, but its large size, long tube. Measuring light curtain detects the light generated by the transmitter is not as common as just a bunch of sensors, but in the longitudinal direction of the light array to generate a given spacing, forming a "curtain", in a scanning mode, with the controller and its software, implement monitoring and measuring object dimensions function. Measuring light curtain system must be equipped with a controller to work properly, the controller is programmed using software, it can provide a variety of scanning modes and detection analysis mode, and can communicate through a serial interface with PLC or computer, or scan transfer control As a result, additional trigger signal can also be connected to control the scanning process.
