DIAPHRAGM SEALS
The Weiss line of Diaphragm Seals, in conjunction
with Weiss
pressure indicators, offers instrumentation that’s rugged and
carefully calibrated
to withstand the most severe industrial,
process or OEM service.Our diaphragm seals are available
in a variety of metal
housing materials and process connection
sizes to fit most requirements.

The Series MD/MN is a compact, lightweight,
economical diaphragm seal. The upper and lower housing, as well as the diaphragm,
are type 316 stainless steel - all welded together making a one piece integral
unit, ideally suited for those applications where space is a factor.
The use of a hermetically sealed, liquid
filled pressure gauge in conjunction with either a MD or MN seal protects
the indicating gauge
from both the process medium and atmospheric conditions,
as well as reduces pointer fluctuations due to vibration and pulsation.
