  • In general, when a sensor has multiple transmitters and receivers, gaps in the sensor's field of view can occur from spacing between transmitters or receivers as well as from practical limitations of real-world transmitters and receivers, such as geometric dimensions and shapes available, actual effective transmission or reception areas, and proportional band or near-linear operation parameters.
