Diaphragm
Seal and Hygienic |
Intended
Service
Diaphragm seal gauges are designed
to avoid any clogging that would
occur in a bourdon tube gauge
and can cope with a greater range
of process temperature and aggressive
product. They can be manufactured
with special materials not available
in bourdon tube gauges and with
a remote reading facility. The
diaphragm seal gauge is particularly
suited to the petro-chemical and
Food industry. |
