Absolute distance measurement
The efector pmd sensor can provide an analogue signal (4...20 mA) that is proportional to the object-to-sensor distance. The analogue output can be scaled. An application for this is level monitoring as shown here at a portioning system.

| Optical sensors with background suppression and ultrasonic sensors are compact and low-cost alternatives for distance measurement but have shorter ranges. Traditional time-of-flight systems offer an improved level of performance but are much higher in cost. The efector pmd sensor combines the advantages of these systems: ranges of 10 m at an extremely attractive price.
