Patent number: 9410626Abstract: A sealing system is provided for preventing leakage of a fluid from a fluid-containing chamber when a sensor probe for measuring fluid conditions within the chamber is inserted into the chamber. The sealing system has at least one port in fluid communication with the fluid-containing chamber. The port has a stem projecting outwardly from the chamber, a tapered flange, and a stem passageway in fluid communication with the chamber interior. A probe seal which is adapted to attach to the stem forms a seal between the port and the sensor probe and prevents fluid in the processing chamber from leaking past the probe seal. The probe seal has spaced-apart inner and outer skirts. The inner skirt forms a seal passageway which is in fluid communication with the chamber, and an inner end disposed to enter the stem passageway when the probe seal is attached to the stem.Type: GrantFiled: July 24, 2013Date of Patent: August 9, 2016Assignee: Pall CorporationInventor: Nigel David Feltham
