Keller Company Digital Pressure Gauge for Hydrogen Applications LEO Record H2

Keller's pressure sensors play a crucial role in hydrogen engine-equipped racing cars. This is because extremely high precision and reliability are essential in hydrogen systems within motorsports. Keller's pressure sensors are used in fuel cell powertrains, supporting the precise monitoring and control of hydrogen and air circuits under harsh high-performance conditions. 〇 Hydrogen Loop Keller's pressure sensors monitor the flow of hydrogen within the fuel cell by measuring optimal pressure levels, contributing to the realization of efficient electrochemical reactions. 〇 Air Loop Accurate pressure measurement is essential for the optimal management of oxygen supply, which directly affects the efficiency and output of the fuel cell. 〇 High-Pressure Hydrogen Line Keller's pressure sensors are widely adopted in high-pressure hydrogen lines, as well as in hydrogen-powered test benches and onboard storage systems. In motorsports, reliability is paramount in a world where every second counts. Additionally, components that can withstand extreme pressures and rapid changes in load under harsh conditions are indispensable. Using Keller products, which boast the highest standards of precision and reliability and are made in Switzerland, is a testament to a deep commitment to quality.

Hydrogen poses a risk of leakage due to its status as the smallest molecule on Earth, which can lead to permeation. It also has highly flammable properties when exposed to air. Therefore, it is crucial to prevent leaks from hydrogen tanks or to detect them early. Keller's pressure sensors are used for leak testing in hydrogen fuel cells. The hydrogen fuel cell has three channels: one for air (oxygen), one for hydrogen, and one for cooling. Nitrogen is used first, followed by hydrogen, to detect leaks within the system. The pressure values at the inlet and outlet of the fuel cell are continuously recorded and displayed on the screen in real-time, allowing for ongoing monitoring. A drop in pressure indicates a leak in one of the three flow paths. Keller's pressure sensors have high accuracy, enabling them to detect leaks even in small areas that are not sealed, ensuring the safe use of fuel cells.

Hydrogen is at the center of energy conversion, bringing unique possibilities for the decarbonization of industries and the transformation of energy consumption. Hydrogen is considered an environmentally friendly fuel because it does not release harmful exhaust gases such as CO₂, nitrogen oxides, and particulate matter when used for energy generation. However, hydrogen gas, regarded as one of the pillars of the future of energy, faces significant technical challenges in terms of storage, transportation, and measurement. How are KELLER's pressure sensors designed to meet these requirements? KELLER's hydrogen market specialist will answer that! (The article can be found through the related link below) 1.
