TMP006

Other Parts Discussed in Thread: TMP006

Hi Ian, 

We are using the TMP006 and are planning on making an enclosure for the sensor like you have done in the video to reduce the effective area. Can you give me more information about the type of material that was used for the sensor enclosure. Any recommended metals that worked better than other in terms of emissivity and overall performance in testing? And does the thickness of the enclosure/depth of the aperture matter? Can you address the thickness of the metal that you used in the video?

Thanks!

    Hello Christopher,

    The covers we have used are provided by a vendor called FotoFab and are made of an alloy called nickel silver. They actually contain no silver, but are made of 55% Cu, 27% Zn, and 18% Ni. There is lots of flexibility in what material can be used, as long as it's a shiny metal which can easily be machined into the required shape. I believe we went with nickel silver as it is a material that FotoFab commonly works with.

    I don't have information on the thickness of the metal right now, but I'm looking into it and will update you soon. The depth of the enclosure itself is shown in the attached slides.

    Thanks Ian for the information. 

    If you come across the thickness of the metal used that would be great or if you have recommended range of thicknesses that would also be very beneficial. 

    Thanks again!

    Hi Christopher,

    The thickness of the metal is not critical as long as you incorporate it into your geometric equations. We use material of 35 mils thickness or thinner.
