| In summary, try to take all these sensor choices and employ a natural order to things. First look to inductive proximity sensors and to capacitive switches. If you solve your application with photoelectric sensors, a good pecking order is to try beam break sensing first, either opposed mode or retroreflective. If you use diffuse mode sensors, be sure to pick the right type of diffuse sensor for the job at hand. If standard diffuse sensors have difficulty, because your target is transparent or semi-transparent, try divergent sensors. Convergent mode is great is for close-range diffuse sensing. If the background is reflective, background suppression sensors can often solve the problem. Fiber optics are great if your target is in an area of high temperature, heavy washdown, or if the target is buried within the works of the machine, making it difficult to mount a standard sensor. For long-range diffuse applications, ultrasonic sensors give you yet another choice. If you need analog feedback, ultrasonic sensors can often help you there. Finally, if you need a linear signal with extremely precise resolution, lasers are available for those types of applications. | |||||
