No one technology will ever take over the world. This is what we all love about the sensing world-it’s very dynamic and ever-changing.
Metal proximity sensors are great for detecting certain kinds of metals, are very affordable and robust but oftentimes operate with very limited sensing ranges. Polarized photoelectric sensors can be used to ignore color differences, too, as long as the space in between products is adequate.Ĭapacitive sensors can be used to detect the presence or level of materials inside of certain packages when sound and light cannot penetrate the packaging materials. Photoelectric sensors are great for either tolerating differences in colors, as infrared LEDs are often utilized, or detecting the difference in colors, like white LEDs do. Ultrasonic sensors are good for ignoring color, texture and material differences, but they may have issues with angle of incidence or speed or limited space between objects. But the more difficult applications require some level of expertise from the supplier, as well as the best technology to solve the problem.
These types of applications require very little technical expertise and can be solved with almost any kind of low-cost sensing technology. Obviously, there are applications that are extremely easy, repeatable and unchallenging. sales, Tri-Tronics: The reason there are different technologies is that each application is unique and may require the best solution. With options that range from ultrasonic and photoelectric sensors to capacitive and inductive proximity sensors, what advice can you give on how to choose the right sensor for the application? Our panel of experts tells you what you need to know. Choosing the right device always entails some forethought, especially when installing it in difficult-to-reach or hazardous areas.
Presence sensing is a broad topic that entails both object detection and machine guarding.
