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
