For years, standard proximity sensors have been used in applications requiring metal detection, ranging from packaging and material handling to agriculture and oil& gas. Engineered as an early solution to achieve consistent metal detection, standard proximity sensors were widely used in a variety of applications, from detecting aluminum cans on an assembly line to sensing a steel gate on a tank. Though a popular solution, these devices present challenges in applications that require reliable metal detection.
