Abstract
A flow head for a gas sensor having a sensing element is provided. The flow head includes a body at least partially defining a cavity in thermal communication with the sensing element. The body includes an inlet port located within an annular surface of the body and an outlet port located within the annular surface of the body. The body also includes an inlet passage offset from and parallel to the cavity, wherein the inlet passage configures the inlet port and the cavity to be in fluid communication with one another. The body further includes an outlet passage offset from and parallel to the cavity, wherein the outlet passage configures the outlet port and the cavity to be in fluid communication with one another.

A flow head for a gas sensor having a sensing element, comprising:
- a body at least partially defining a cavity in thermal communication with the sensing element, and including:
- an inlet port defined within an annular surface of the body;
- an outlet port defined within the annular surface of the body;
- an inlet passage offset from and parallel to the cavity, wherein the inlet passage configures the inlet port and the cavity to be in fluid communication with one another;
- and
- an outlet passage offset from and parallel to the cavity, wherein the outlet passage configures the outlet port and the cavity to be in fluid communication with one another.
A gas sensor, comprising:
- a sensing element;
- a heating element disposed proximal the sensing element;
- a housing configured to at least partially surround the sensing and heating elements;
- and
- a flow head connected to the housing to at least partially define a sampling chamber, the flow head comprising;
- a body configured to receive the sensing and heating elements;
- an inlet port located within an annular surface of the body;
- an outlet port located within the annular surface of the body;
- an inlet passage offset from and parallel to the cavity, wherein the inlet passage configures the inlet port and the cavity to be in fluid communication with one another;
- and
- an outlet passage offset from and parallel to the cavity, wherein the outlet passage configures the outlet port and the cavity to be in fluid communication with one another.
