Quick-release diaphragm seals, with clamp connection Quick-release diaphragm seals are available for the following SITRANS P pressure industrial 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 industrial seal means that quick dismounting is possible for cleaning.
