Sensor technology is indispensable for industrial applications. It facilities the work, optimizes processes through automation and gives additional safety. One of their main tasks is the detection of distances. With this information it is possible to recognize and monitor variations of the distance between sensor and object. A useful function for keeping a safe distance, positioning or accurate measurement of objects over range. The precision and reliability of measurement technology is very important for industrial applications. If the detection is disaffected or vague, damages on machines, objects, and people can be occurred or the work and management will be inefficient. Two typical use cases of high-accurate distance measurement are level determination and collision avoidance. For level measurement applications the sensor knows the distance to the filled material or bottom of tank and captures the variations when something will be filled in. Distance measurement is also needed to prevent collisions. Sensors continuously detect the distance between sensors placed on pallet trucks or off-road machines and trigger an alarm to avoid a possible collision.
