I found in my notes that the previous cables were 10', is that still a good length? As soon as I get confirmation from you I'll start cutting the wires.</div>

I'm afraid that due to some family medical issues, my schedule is not too concrete right now. It would be best if you ordered the supplies, so I can spend all the time I do have on fabrication. I haven't had a chance to look through my old log book, so if you
could figure out the overall length of the wires it would also be helpful.<br>

<div class="" style="word-wrap:break-word; line-break:after-white-space">Dear Mindy,
<div class=""><br class="">
</div>
<div class="">Sorry for the late reply and for not sending in the request to this email group earlier. As you mention, we need 48 regular RTDs and 6 with feed throughs. I attach pics of how these RTDs were done in the past:</div>
<div class=""><br class="">
</div>
<div class="">1. Pic of heat shrink around the RTD wire to support the soldered joint</div>
<div class="">2. Blue ferrels</div>
<div class="">3. RTDs with feedthrough structure. As you can notice, the short side of the feedthrough carries a smaller length of wire. In the past we used 6” to 8” of wire but this time, the pumping chamber will be slightly larger than before so I expect
the lengths to be slightly longer than last time. Let me get back to you about the exact lengths on each side. Please go ahead and order the parts in the meantime or let me know if you would like me to order them.</div>
<div class=""><br class="">
</div>
<div class="">Thanks again for your help!</div>
