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:
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.
