When looking at Ultrasonic Sensor Technology one of the most problematic areas of application is false positive outputs due to a large operating angle. It is not uncommon to have an Ultrasonic Sensor in an application where the sensor has such a large degree of operating angle that the senor is detecting an object other than the desired target. In my past blog post I explained in detail the “Blind Zone” and how important it is to understand your minimum working area. In the video below you’ll see that Ultrasonic Sensors can offer a tight precise “Operating Angle” that detects a desired target without detecting other obstacles that may be present within the application area.
