Dwyer Series AT23000MR & AT23000MRS Approved Photohelic Switch/Gage,
with 24 VDC Power Using solid state technology, the Series AT23000MR & AT23000MRS ATEX/IECEx
Approved Photohelic® Switch/Gage with 24 VDC Power combines the functions
of a precise, highly repeatable differential pressure switch with a large easy-to
read analog pressure gage. Gage reading unaffecte by switch operation and
will indicate accurately even if power is interrupte. AT23000MR series employ
