The picture of this part and the drawing do not match. They are mirror images of each other. Can post pictures of the actual product? With the cable pointing to the left, I would like to know if the mounting hole is above or below the cylinder. Thanks
Please direct you question to temp@omega.com so your question can be fully investigated by an application Engineer.

Can RTD-831 series be used in Vacuum chamber like RTD-830 series? Thanks.
Hi Anonymous,
If used in vacuum there may be some outgassing from the epoxy used in construction; so we have no vacuum recommendation for this product; You would need to purchase and evaluate to see if would be acceptable. This has the same construction as the RTD-830. The new washer shape provides for stronger lead wire connection.
