Sandia’s Robust, Wide-Range Hydrogen Sensor overcomes the limitations of existing hydrogen sensing technologies.
Sandia


The hydrogen sensors were microfabricated for minimal size, weight, and power consumption. A temperature detector and heater were included on the sensor for temperature control. Two palladium chrome (PdCr) hydrogen detection devices were included in each sensor package: a Schottky diode for low concentrations and a resistor for high concentrations. These sensor designs allow operation in inert environments. "Smart" electronics developed by Makel Engineering were integrated with the sensors to control the sensor temperature and process the output of the various sensors.
