SITRANS P measuring instruments for pressure
Quick-release diaphragm seals
For gage, absolute and differential pressure
■
Overview
2
Quick-release diaphragm seals, to DIN 11851 with slotted union nut
Quick-release diaphragm seals, with clamp connection
Quick-release diaphragm seals are available for the following
SITRANS P pressure transmitter series:
• For pressure: MK II, DS III, DS III PA, DS III FF
• For differential pressure and flow: DS III, DS III PA, DS III FF
The quick-release remote seals are common designs in the food
industry. Their design means that the measured medium cannot
accumulate in dead volumes. The quick-release clamp present
on the remote seal means that quick dismounting is possible for
cleaning.
