Construction
The interior temperature sensor is not
vented and consists of an integrated
thermo-optical sensor, an NTC element in
combination with a photodiode.
The NTC element measures the
temperature and intensity of solar radiation
on its surface. This allows the sensor to
measure the air temperature in the
vehicle’s interior even if the sensor's
surface is heated. The sensor signals are
transmitted to the Climatic or Dual Zone
Climatronic. Software then evaluates the
sensor signals and regulates the
temperature of the vehicle’s interior.
