Abstract
What is disclosed is a hydrogen sensor (100) having a housing (101) that includes a cavity (102) and has a passage opening (103) from the cavity (102) to a gas connection of the hydrogen sensor (100) or an environment, having a first hydrogen sensor element (104), disposed in the cavity (102), for measurement of a hydrogen content in the cavity (102), having a first sorption element (105) for sorption of water and/or water vapor, especially an adsorption element (105) for adsorption of water and/or water vapor, and having a first heater (106) for bakeout of the first sorption element (105), wherein the first sorption element (105) has open pores and is disposed in the passage opening (103).
Claims22
A hydrogen sensor, comprising:
- a housing that comprises a passage opening from a gas connection of the hydrogen sensor or an environment to an outer cavity;
- a hydrogen sensor element, arranged in an inner cavity, configured to measure a hydrogen content in the inner cavity;
- a sorption element for sorption of at least one of water or water vapor, wherein the sorption element has open pores and is arranged within the housing between the outer cavity and the inner cavity, wherein the inner cavity has an inner cavity opening that faces away from the passage opening;
- and
- a heater for bakeout of the sorption element, wherein the sorption element is disposed atop the heater.
