Based on acoustic waves and their reflection, these waves work by the body.
From Ultrasonic sensors They are also used to measure distances. The reflected signal returns from the target to the sensor and is measured, the time between sending and receiving the sound pulse is proportional to the distance between the sensor and the target.
Performance Ultrasonic sensors It is independent of the color and smoothness of the body surface and the ability to remove the background effect (Background suppression) in these sensors is excellent.
The output of these sensors is analog (current or voltage) or digital.
If the sensor head is impregnated with oil, adhesives, dust and. . . The sensor will not malfunction.
In case of deviation of the piece (up to 8 degrees), there is no change in the measured value.

Color detection sensors
Color recognition sensors in lines and assemblies are used to identify specific objects. The most important issue in these sensors is the detection of near or very bright colors.
For example, the metallic used in the auto ironing industry makes color recognition difficult.
The efficiency of a color recognition sensor is determined by the number of colors it can detect, the ability to quickly change parameters, or the ability to recognize multiple colors simultaneously.
Conventional color detection sensors have a white LED with a high light output that reflects modulated light onto the target.
The reflection of light from the surface of the object is analyzed to distinguish the main colors red , green and blue. This information is for whether the parts are correct or not
Is used. In some applications, the device user places a sample color in front of the sensor and programs it to detect this color.
During the operation, the user can also define an interval for the color, thus confirming the objects whose color is in this interval. This operation and adjustment of the upper and lower points is done by trial and error and does not have proper accuracy. Some color detection sensors have only one output, which is to confirm and reject. Thus, by connecting to the control system, they determine whether the object passing in front of the sensor is correct or not. But in many other processes, the focus is on deeper monitoring, not just acceptance or rejection. The new generation of color recognition sensors produce three more outputs that express the intensity of the colors red, blue and green. This feature allows for more precise and intelligent control of the process.
New color recognition sensors can be used for applications that require expert color recognition systems.
Automated systems can use the differences detected by color recognition sensors as input to the control system. For example, color integrity is very important during the textile production process. The density level of all three primary colors can be continuously monitored by these sensors and small changes in color can be slowly corrected.
