Abstract
A convective heat transfer increaser feature for a process sensor. The feature may include at least annular fins, helical fins, knurling or other features which increase surface area. The features also increase turbulence which increases adherence of the turbulent flow to the process sensor.
Claims14
A process sensor assembly, comprising:
- a temperature detector;
- a temperature detector housing structure wherein said temperature detector is disposed;
- a potting material within said housing;
- and
- a plurality of helical fins disposed on an outside of said temperature detector housing structure,
- wherein said fins create turbulence causing increased film attachment in an air flow along a side of the temperature detector, and increase surface area of said temperature detector housing structure, increasing convective heat transfer.
3 more elements
A temperature sensor assembly, comprising:
- a sensor housing capable of insertion in an airflow;
- a temperature detector disposed within said sensor housing;
- a potting material within said sensor housing;
- and
- an exterior of said sensor housing having a fin at an angle of 0 to about 90 degrees relative to said airflow, wherein the fin includes at least one continuous helical fin that creates turbulence in the airflow causing increased film attachment on at least one side of the sensor housing.
2 more elements
A process sensor assembly, comprising:
- a processor sensor assembly housing having a temperature detector positioned therein;
- and
- a plurality of helical fins generally symmetrically disposed about said housing, and disposed at an angle to an airflow of less than 60 degrees, wherein said fins increase convective heat transfer by creating turbulence in the airflow causing increased film attachment along a side of the processor sensor housing and increasing the surface area of said temperature detector housing structure.
