Abstract
Embodiments relate generally to systems and methods for normalizing the pressure proximate to a gas sensor within a gas detector. A rectifier assembly for use with a gas detector may comprise a flow barrier; a first valve connected to the flow barrier configured to open to normalize the pressure proximate to the gas sensor; a second valve connected to the flow barrier configured to open to allow airflow from the pump toward the gas sensor; and one or more retainer rings configured to position the first valve, second valve, and flow barrier with respect to one another, and configured to position the rectifier assembly within a cavity of the gas detector, wherein the rectifier assembly is configured to be located between a pump and at least one gas sensor of the gas detector; and wherein the rectifier assembly is configured to normalize pressure proximate to the gas sensor.
