Results of the investigation of thin Pd layers as hydrogen sensors are presented. Two types of sensors are examined - resistance and optical sensors. Changes in measured signal as a function of hyfrogen concentration in hydrogen-nitrogen mixture are registered. The sensor is exposed either directly to the gas mixture or to the transformer oil, through wich the gas mixture passes. The hydrogen concentration in the mixture changes from 0.5% to 4%. Investigated sensors are sensituve enough in this concentration range, in both media. Changes of Pd film properties caused by hydrogen absorption are reversible except a few first exposures to the mixture. Obtained results confirm the possibility of developing simple sensor for detection of hydrogen gas in dissolved in the transformer oil.
