ABSTRACT:
An explosion-proof gas sensor has a measuring element (2), which generates a measured signal that depends on the concentration of the measured gas and is delimited against the environment by means of a porous, gas-permeable and sintered metal body (7). The sintered metal body (7) has a high mechanical stability, so that the use of additional components, which hinder the diffusion of the gas to be measured into the gas sensor and thus prolong the response time of the gas sensor, can be eliminated.
