Background:
In the future, it is hoped that “green” hydrogen produced using renewable energy will become a key component of a sustainable and climate-friendly energy economy. Although we can’t see or smell hydrogen, it burns and explodes easily when it comes into contact with air. Historical events, such as the explosion of the Hindenburg Zeppelin and the recent explosion of the Norwegian hydrogen refueling station, show how important safety precautions are if we are to build a sustainable and safe hydrogen economy. At this time, H2 sensors will play an important role in people’s production and life.
Hydrogen gas monitoring
H2 sensors can successfully identify even low concentrations of gas, such as the presence of a leak in a pipe. The innovative hydrogen sensor, designed by FAU researchers, consists of tiny particles called superparticles that make hydrogen visible to the naked eye without power or sophisticated equipment. The superparticles are between 1 and 10 microns in size, with a micron equivalent to a thousandth of a millimeter, and incorporate a purple indicator dye called lapis lazuris. When they come in contact with hydrogen, the molecules in the dye react in two different stages and change color significantly. If the sensor turns pink, it indicates a hydrogen leak. If the hydrogen is still leaking and the sensor is in contact with a lot of hydrogen, it becomes colorless. Immediate response makes leaks visible and allows them to be discovered in real time. Another advantage of innovative hydrogen sensors is their small size, making them suitable for many different scenarios, such as pipe coating.
TOP3 Introduction to Common H2 sensors
Fixed H2 gas detector- Explosion-proof
Fixed gas detector, stable performance, sensitive and reliable. With high-precision liquid crystal display, explosion-proof housing, diffusion type or pump suction type. The Combustible gas detector has the characteristics of flexible use and simple operation. The Combustible gas detector is used in various gas leakage places, such as: city gas, petroleum, chemical, pharmaceutical, steel, special industrial plants and other fields. The explosion-proof level of the Combustible gas detector is CT6.
Details:
(1) Quality assurance of high-quality probes: We use a variety of high-quality probes to ensure that the probes are sensitive and have a long life;
(2) Fine workmanship, waterproof and dustproof: double waterproof treatment for shell seam/wire interface, waterproof grade up to IP65;
(3) Die-cast aluminum shell with high explosion-proof grade: the shell is Exd II CT6 explosion-proof to protect the internal components;
(4) The probe protection is meticulous and thoughtful: the stainless steel mesh protects the probe part, which does not affect the gas in and out while protecting the probe;
(5) Double protection of sound and light alarm: the alarm can produce a siren sound of nearly 80dB(A), and is supplemented by red light prompts, which is strong in warning.
