Hi Mindy,

Thank you very much for the inventory. The order I placed 30 days ago seems to have gotten stuck at the PR stage due to a price difference issue. I did an additional PR to account for the price difference and resubmitted it for approval. With the ones you currently have, you should be able to make two sets which should be good for us to get started.

The 6 cables with feedthroughs should need only 12 RTDs. Two of the holes should be left empty. Please see attached pic.

Best,

Arun

Hi Arun,

I have checked the inventory. I received 28 RTDs. I need 66, plus spares. In my original email I stated I needed 15 packs of 5 RTDs, for a total of 75. There are six cables with feed throughs, these require 24 RTDs and 42 single twisted pairs, these require 42 RTDs. I have started with what I have. I will need an additional 47.

Thanks,

Mindy

Dear Mindy,

I talked with Mark and got the green signal and codes to place order for all the materials needed to make RTDs. Do you have sometime today or on Monday to help me place an order? Sorry I haven’t done this before and don’t want to accidentally buy stuff not needed.

Best,

Arun
