382102289 XCMG GR2605 motor grader solar radiation sensor

382102289 XCMG GR2605 motor grader solar radiation sensor

The 382102289 is a dedicated solar radiation sensor for construction machinery (compatible with XCMG GR2605 graders, etc.). It collects ambient sunlight intensity signals to provide data for air conditioning systems, driver’s cabin temperature control, and operating mode adjustments, enhancing equipment intelligence and driver comfort.

Core Functions and Roles

* Real-time monitoring of external sunlight intensity, converting light signals into electrical signals for transmission to the equipment control system;
* Assisting the air conditioning system in automatically adjusting cooling/heating power to match changes in the cooling and heating load of the sunlight environment;
* Participating in driver’s cabin temperature control logic calculations to optimize airflow patterns and temperature settings, reducing manual intervention;
* Adapting to the harsh operating conditions of construction machinery, possessing anti-interference, temperature resistance, and vibration resistance characteristics to ensure signal stability.
