Hi Carlos,</div>

During the last collaborator's meeting you mentioned that there were already some temperature sensors in the crystal zone.</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0);background-color:rgb(255,255,255)">
I have a few questions for you:<br>
</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0);background-color:rgb(255,255,255)">
How many sensors are there, and what kind are they?</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0);background-color:rgb(255,255,255)">
I seem to recall them being RTDs (PT100s specifically), is that correct?</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0);background-color:rgb(255,255,255)">
Also, are they 2, 3, or 4-wire?</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0);background-color:rgb(255,255,255)">
You would like to have them integrated into the interlock system we're designing?</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0);background-color:rgb(255,255,255)">
Do you have any documentation detailing exactly where they are located?</div>

Thanks for any information you can provide. This will really help us with designing the interlock system.</div>
