TI TMP006 and TMP007 industrial cover

Other Parts Discussed in Thread: TMP006

I have the TMP006 part installed on the PCB but need to test it with actual industrial cover. Our product is meant for moisture resistance and construction applications. The moment I place any plastiglass or other object to protect it from elements, the radiated heat from the target is effectively blocked and I can not read. Is this part meant for other applications that do not require any safety cover at all? If I must have A CLEAR FIELD OF VIEW than why is this not clearly stated in all documentation?

Thanks

  • Which material can we use to cover the TMP006/TMP007 and the PCB in order to protect them from elements and let the IR wave pass through? (temp range -10 °C to 50 °C)
    Where can we buy samples of these material and do some test?
  • Good morning Daniele,

    I already posted similar question on line but no reply jet. 

    We are using both TMP006 and TMP007 and any cover has two negative effects on this part:

    1. Reduced range of temperature sweep - clipping

    2. Huge jumps during testing - Delta swing

    We are trying to combat this by dynamically edit the "Temperature coeficcient" value.

    ..any cover you end up using will provide a radiant heat wall, making the reading different compare to the actual object temperature.

  • Hi Peter/ Daniele,

    We received another question recently on TMP006/007 covers and I believe we missed/confused this ones. We apologize the late reply. Tommy Santoyo is the IR sensors specialist and he will get back to you as soon as he get a chance with responses to your questions. On the meantime I will share with you the link of the other forum post where he discuss some ideas for TMP006/007 metal covers.

  • Hello Peter and Daniele,

       Thanks for your questions, I’m glad to help.  First of all let me start by saying that many, actually most materials block IR.  There are a few material that will pass IR at different wave lengths.  Our TMP06/007 part has a Silicon body that passes IR wavelength’s between 6 and 16um.  See the chart below.  These materials can be quite expensive.  We have found that you get pretty good transmission using polypropylene the same material that a milk jug is made of. Edmund Optics carries what they call Poly  IR Material Window.  It passes 8 to 14um.  The link is below.  The problem with this material is it has a relatively low tolerance for temps over 100C.

      I believe your problems are related to this issue and if you have further questions, I’ll be glad to help.

    Regards,

    Tommy Santoyo
