1-2 Mechanism of Temperature Measure-
ment and Monitoring
This section shows each model and the model configuration of the Main Unit and the infrared thermal
sensor.
The measurement field of view of an infrared thermal sensor is made of the following elements.
With one segment as 8 pixels × 8 pixels, the measurement field of view is made of 16 segments per
infrared thermal sensor.
In the Main Unit, the alarm threshold is set in the "segment" unit rather than the pixel unit or the infrared
thermal sensor unit, and alarm determination is performed.
