Abstract
An exhaust gas aftertreatment system includes: a first sensor configured to measure a parameter in the exhaust gas aftertreatment system; a second sensor configured to measure the parameter in the exhaust gas aftertreatment system, the second sensor disposed proximate the first sensor; and at least one controller configured to alternately receive sensor values from the first sensor for a first target period of time, and receive sensor values from the second sensor for a second target period of time.
Claims9
An exhaust gas aftertreatment system comprising:
- an exhaust gas conduit comprising a peripheral wall;
- a first sensor attached to the peripheral wall of the exhaust gas conduit and configured to measure a parameter in the exhaust gas aftertreatment system,;
- a second sensor attached to the peripheral wall of the exhaust gas conduit and configured to measure the parameter in the exhaust gas aftertreatment system, the second sensor disposed proximate the first sensor;
- and
- at least one controller configured to alternately:
- receive sensor values from the first sensor for a first predetermined period of time, and
- subsequently receive sensor values from the second sensor for a second predetermined period of time,
- subsequently receive sensor values from the first sensor for the first predetermined period of time, and
- subsequently receive sensor values from the second sensor for the second predetermined period of time.
