Jebool supplies a fully automatic hydrogen (helium) leakage data acquisition system for hydrogen fuel cell vehicles to meet the real-time monitoring of hydrogen or helium leakage during the crash test of hydrogen fuel vehicles and the measurement of helium concentration in the vehicle. The data acquisition system can monitor up to 8 gas storage tanks at the same time, collect real-time data on the pressure and temperature in the tank, and simultaneously calculate and display the current leakage situation, escorting the safety of the crash test.           The equipment is designed and developed with reference to UN ECE R134, and can be calculated in real time at 1 Hz to display the current leakage. During the test, the data can be synchronized to the computer or mobile phone via WiFi, and the data is stored inside the device. The device interface is as follows:

• Provide 8 pressure inputs (connect directly to the pressure sensor of the hydrogen storage tank);
• Provide 8 temperature inputs (connect directly to the temperature sensor of the hydrogen storage tank);
• Provide 4 channels RS485 input (can be connected to JEBOOL He or H2 concentration sensor);
• Provide 8 digital inputs (can monitor any switch signals such as valves simultaneously);
• Provide trigger input interface (T0 input, SR trigger can be software input);
• Provide 2 alarm outputs;
• Status indicator (external power supply, battery level, start recording, data in it, T0 trigger, Ethernet communication, WiFi communication);
• Bus interface (compatible with Jipu insulation tester RES-1000A bus);
• Switch machine button (valid for 3 seconds long press);
• Built-in 3-axis acceleration sensor (for T0 trigger);
• Built-in rechargeable battery, working time> 4 hours;
• Built-in data storage, record length> 3 hours;
• The body adopts a high-strength nylon shell, full LEMO connector, can be installed with a mounting plate or direct side ear screws, impact resistance >100g.

      The software can display the pressure, temperature, leakage and helium (or hydrogen) concentration of each hydrogen storage tank in real time during the test; the data in the equipment can be downloaded after the test. Provide Excel data format (other formats can be customized) and original data, the original data can be loaded into the software to playback and view. At the same time, Jebool provides He-20A He gas concentration sensor with optional analog or RS485 interface.

     In order to installing the on-site operation of engineers, cables can be customized according to the sensor interface of the hydrogen storage tank, which saves operation time and improves reliability.
