Study Notes

Temperature Sensor Installation Types

Two types of temperature sensors are used: duct and zone sensors.
Duct sensors measure airflow temperature directly.
Duct sensors send data to the zone controller.
If a duct sensor fails, the zone controller closes the corresponding trim air valve.
To prevent this, some aircraft have two sensors in one housing.
Zone sensors are installed in the cabin ceiling.
Each zone has at least one zone sensor.

Temperature Sensors

Aircraft use two main types of temperature sensors: duct and zone.
All sensors are thermistor-type.
Duct sensors measure airflow temperature directly.
Duct sensors send signals to the zone controller.
If a duct sensor fails, the zone controller usually closes the corresponding trim air valve.
Some aircraft have dual sensors in one housing to prevent valve closure in case of a single sensor failure.
Zone temperature sensors are installed in the cabin ceiling area.
Each zone has at least one zone sensor.
