Hydrogen sensor

They are considered low-cost, compact, durable, and easy to maintain as compared to conventional gas detecting instruments.

[6] Palladium sensors have to be protected against carbon monoxide, sulfur dioxide and hydrogen sulfide.

Several types of optical fibre surface plasmon resonance (SPR) sensor are used for the point-contact detection of hydrogen: Sensors are typically calibrated at the manufacturing factory and are valid for the service life of the unit.

Siloxane enhances the sensitivity and reaction time of hydrogen sensors.

[5] Detection of hydrogen levels as low as 25 ppm can be achieved; far below hydrogen's lower explosive limit of around 40,000 ppm.

Greg Glatzmaier, at the National Renewable Energy Laboratory , determines the high-temperature thermal and mechanical stability of sealants used in a lab prototype of the integrated hydrogen sensor separator module.
