Field of View Diagrams:
Please note: The given measured spot size contains 90% of the energy detected by the sensor. We normally recommend
the target is at least twice as large as the given measured spot for maximum accuracy. Sensors may be used at longer
distances than the above diagrams show. There is no maximum measurement distance in clean air; this is because the
PyroMiniBus detects only the wavelengths of infrared radiation that are not absorbed by the atmosphere.
