Electro Optical Components offers state of the art hydrogen sensor products. The technology uses a patented nano thin-film technology (palladium alloy) with key advantages in hydrogen sensing. The sensor technology uses a thin film palladium alloy that absorbs and desorbs hydrogen as it comes in contact with the sensing device. Hydrogen is measured specifically by a change in bulk resistance as a function of concentration.

The sensors utilize catalytic thin film resistors made from a Pd / Cr alloy to measure hydrogen. The resistance of Pd film increases monotonically when exposed to hydrogen. The system measures these changes and displays the hydrogen concentration. The sensor chip also include a micro-thermometer and micro-heater for maintaining constant chip temperature. This elevated, controlled temperature assures that sensor operation is unaffected by ambient or process gas temperature. No other reference gases or environmental controls are necessary during measurements.

These hydrogen sensor products use a proprietary composite coating that inhibits penetration of most contaminant gas species from poisoning the sensor surface. The proprietary coating preferentially allows hydrogen to pass through and blocks larger molecules such as hydrogen sulfide (H2S), carbon monoxide (CO), carbon dioxide (CO2), methane (CH4), ammonia (NH3), halogens like chlorine (Cl2), and nitrous oxides (NO, NO2).

Compared with other technology used in hydrogen sensors, this technology has the following advantages:

• No interference by other gas, only responds to hydrogen.
• No oxygen is needed during use. It works in harsh environments and sealed systems.
• No consumable material is needed, giving it a long life span (10 years) and easy to maintain.
• Precise & reliable result, high accuracy – ±0.5% ~ ±5% F.S
• Faster response time – T90 < 60s
• Good for a variety of conditions; Working temperature -20~+100° and Humidity up to 95%RH

Applications for these hydrogen sensor products include industries such as:

• Hydrogen gas production & storage
• Oil and gas industry, process analysis
• Chemistry industry, process analysis
• Fuel cell production and use
• Nuclear power plant monitoring
• Power generator and transformer online health monitoring

Hydrogen (H₂) can be dangerous because it is flammable & explosive. Hydrogen has NFPA 704’s highest rating of 4 on the flammability scale. For safety it is important to have a Hydrogen Specific monitor in many industries where hydrogen can be generated. Now there are hydrogen sensors that are very compact, have a long life span and are easy to maintain.

Electro Optical Components offers the hydrogen sensors that are the best option for safety, process automation and system automation. With their Pd alloy thin film solid state hydrogen sensor technology you can detect hydrogen leaks quickly. Thanks to the “hydrogen specific” design there is no cross sensitivity to other gases. No misses or false alarms like other hydrogen sensor technology.

Applications include:

• Hydrogen gas production and storage
• Oil and Gas industry
• Fuel cell production and use
• Nuclear power plant monitoring
• Power generation and transformer online health monitoring
