The measuring light curtain consists of an emitter and a receiver. First, a light emitter channel emits a light pulse, and the corresponding receiver simultaneously searches for this pulse. When it is found, one channel scanning is completed, and then it moves on to the next channel. This continues until all scans are completed. After one cycle of scanning finished, the system records which channels are illuminated and which ones are blocked, and outputs a signal according to the system definition, which can be an analog signal, a switching signal, or an RS485 communication signal.
Common functions of measuring light curtains include: 1. Online detection to measure dimensions, sizes, and volumes; 2. Precision correction to align and center (to detect the offset of cardboard, steel strip, etc.); 3. Hole detection, defect detection; 4. Edge detection; 5. Center positioning; 6. Tension control; 7. Component counting; 8. Sorting and piling; 9. Product size detection and measurement, and so on.
ESPE measuring light curtain is with high accuracy and stable performance. It can detect and measure the external dimensions of a car through infrared rays online automatically and without contacting the car.
However, when using the ESPE measuring light curtain, the following precautions should also be noted:
1.When using the measuring light curtain, avoid sunlight shining and water on the lane within the range to be measured,.
2.Ensure the flatness of the ground to avoid measurement errors caused by the uneven ground.
3. In the lane area, anti-rain devices should be installed for the car measuring light curtain to avoid damage caused by equipment dampness.
4. Arrange the lines properly to make it more convenient for the staff to operate the measurement and improve work efficiency. Usually, the maintenance work of the safety light curtain should be done well.
