COMBUSTIBLE GAS SENSORS INCLUDING COMPOSITE SUPPORT STRUCTURES AND COMBUSTIBLE GAS SENSORS WITH MULTIPLE ACTIVE ELEMENTS Russian patent published in 2017 - IPC G01N27/16 

FIELD: physics, instrument engineering.

SUBSTANCE: claimed group of inventions relates to the combustible gas sensor. The claimed group of inventions includes sensors for combustible gases and the operation method of the combustible gas sensors. Moreover, the combustible gas sensor comprises at least the first sensing element containing the first conductive element with an average diameter of less than 20 microns, and electrically connected to the electronic circuit, the combustible gas sensor further comprises the first support element having the first and the second fixed end and an intermediate portion extending between the first fixed end and the second one, and the intermediate portion provides support to the first conductive element, wherein the first support element is characterised by the coefficient value calculated as a ratio of its tensile strength, expressed in pound-forces per square inch (psi), to the heat conductivity expressed in watts / (cm⋅°C) more or equal to 250,000.

EFFECT: invention provides the reduction of the energy consumption requirements for the element operation in a certain temperature range, and also its increase to the maximum strength / bearing capacity at the simultaneousl reduction of the heat loss.
