Hitachixin Co., Ltd. PDM200 gas sensor

PDM200 automotive hydrogen sensor

Overview:

"Safety Guidelines for Hydrogen Fuel Cell Vehicles" organized by the Association of Automobile Manufacturers Automobile Manufacturers Association)2019Edition)》on2019Year10moon26Officially released on the same day. The guideline and the documents it cites clearly require hydrogen fuel cell vehicles to be equipped with hydrogen sensors or hydrogen leakage detection devices. Hitachi Co.,Ltd. relies on years of professional experience accumulated in the field of hydrogen detection,comprehensively compares various hydrogen measurement technologies,and adoptsNASAAerospace-grade hydrogen detection is combined with the company’s palladium alloy hydrogen detection technology applied in nuclear island containment to develop a new generationPDMSeries of vehicle-mounted hydrogen sensors.

working principle:

Palladium alloy thin film hydrogen sensor technology mainly utilizes the catalytic decomposition effect of metal thin films on gases. Hydrogen molecules are adsorbed to the surface of the alloy film. Under the catalysis of the palladium alloy film,the hydrogen molecules are decomposed into two hydrogen atoms. The hydrogen atoms diffuse into the palladium alloy lattice,causing lattice expansion and phase,resulting in the conductivity of the alloy film.,according to this characteristic principle,the measurement of hydrogen concentration can be achieved.

Product introduction:

PDMThe series of hydrogen sensors have high selectivity for hydrogen measurement and a wide detection range of hydrogen concentration. They can accurately and reliably detect hydrogen in oxygen-free and high-temperature environments and are not affected by condensation water. Their life and good shock resistance are suitable for hydrogen applications. Application in energy vehicle field.

Features:

·High selectivity for hydrogen measurement

·Wide measuring range,enabling full range measurement of explosion limit and even pure hydrogen

·service life,up to10Year

·With self-test and self-diagnosis functions
