Abstract
Apparatuses, systems, and methods for in-line gas sensor. The gas sensor includes an first circuit board which supports an illumination source and a second circuit board which supports a detector with a sample chamber positioned between the first and the second circuit board. A gas sample passes through the first circuit board and the second circuit board to enter/exit the sample chamber. Each circuit board may have one or more flow apertures which allow the gas sample to pass through the circuit board to get to/from an interior of the sample chamber.
Claims23
An apparatus comprising:
- a first port;
- a second port;
- an illumination circuit board comprising a light source configured to generate illumination light;
- a detector circuit board comprising a detector configured to measure a received portion of the illumination light;
- and
- a sample chamber positioned between the illumination circuit board and the detector circuit board, wherein the sample chamber is in fluid communication with the first port through the illumination circuit board and wherein the sample chamber is in fluid communication with the second port through the detector circuit board.
An apparatus comprising:
- a sample chamber;
- an illumination carrier comprising a first port and a first substrate having a front side and a back side opposite the front side, the front side of the first substrate configured to face the sample chamber, wherein the input carrier comprises a light source positioned on the front side of the first substrate wherein the first port is fluidly coupled through the first substrate to an interior of the sample chamber;
- and
- a detector carrier comprising a second port and a second substrate having a front side and a back side opposite the front side, the front side of the second substrate configured to face the sample chamber, wherein the detection carrier comprises a detector positioned on the front side of the second substrate, wherein the second port is fluidly coupled through the second substrate to the interior of the sample chamber.
A method comprising:
- receiving a gas sample in a sample chamber through a first circuit board;
- detecting a concentration of a target gas in the gas sample by passing light from an illumination source on the first circuit board through the sample chamber to a detector on a second circuit board;
- and
- exhausting the gas sample from the sample chamber through the second circuit board.
