Abstract
A method and an assembly for sensing a process parameter are provided. The sensing assembly includes a base and a sensor assembly. The sensor assembly includes a sensing element, a first flow channel, and a second flow channel. The first flow channel includes a converging segment, a straightening segment, and a turning segment wherein the turning segment includes a turn radius configured to separate particles from a flow entering the turning segment and the second flow channel is configured to generate a low pressure area downstream of the sensing element. The sensing assembly also includes an extension member extending between the base and the sensor assembly.
Claims20
A sensing assembly comprising:
- a base;
- a sensor assembly, said sensor assembly comprising:
- a sensing element;
- a first flow channel comprising a converging segment, a straightening segment, and a turning segment, said turning segment comprising a turn radius configured to separate particles from a flow entering said turning segment;
- and
- a second flow channel substantially parallel to said first flow channel and configured to generate a low pressure area downstream of said sensing element;
- and
- an extension member extending between said base and said sensor assembly wherein said extension member comprises a first leg and a parallel second leg defining a third flow channel therebetween, said third flow channel substantially parallel to said first and second flow channels.
A method of sensing a process parameter, said method comprising:
- channeling a flow of fluid through a first flow passage defined between a first leg and a second parallel leg of an extension member;
- channeling the flow of fluid through a second flow passage defined between a first airfoil body and a center airfoil body;
- channeling the flow of fluid through a third flow passage defined between a second airfoil body and the center airfoil body, wherein the first, second, and third flow passages are each substantially parallel to each other;
- turning the flow of fluid in the second flow passage to facilitate separating the flow of fluid in the second flow passage into a first stream having relatively reduced particulates with respect to a second stream;
- and
- directing the first stream to a sensing element.
A process sensing system comprising:
- an extension member comprising a first leg and a parallel second leg defining a first flow channel therebetween;
- and
- a sensor assembly extending between said first and second legs, said sensor assembly comprising:
- a center airfoil body and a sensing element positioned downstream of said center airfoil body;
- a first airfoil body spaced apart from said center airfoil body by a second flow channel, said first airfoil body comprising a concave surface facing said center airfoil body;
- and
- a second airfoil body spaced apart from said center airfoil body by a third flow channel, said second airfoil body comprising a convex surface facing said center airfoil body, wherein said first, said second, and said third flow channels are each substantially parallel to each other.
