They are, and I am too in this particular issue. The Potter equipment does not comply with the engineers drawings which is very commonly found and used in other applications. It is a single unit that mounts on the top and does both jobs (level and temp) at the same time.
I have not been successful in find one that sends the 2 signals regardless of listing - which is of course a concern as well. The non listed, single signal units are very inexpensive, but can't use them. The Potter devices are Listed and send 2 signals, but they don't fit the rest of the picture.
