H2 Tank Control
What is a H2 Tank Controller
The H2 Aero Tank Controller manages all essential functions of a cryogenic hydrogen tank system under all flight conditions. It controls the refueling valves, monitors the fill level, temperature, and stable tank pressure, and ensures a reliable supply to the fuel cell.
For maximum adaptability, the system is divided into two modules. The Tank Control Unit (TCU) provides the communication interfaces and processing power and controls all outputs, while the Tank Data Acquisition Module (TDAM) reads most sensor interfaces and transmits the data to the TCU via a bus interface. This split architecture offers great flexibility regarding changes to the sensor interfaces.
Features
