NeSSI™ History

A Complete History - NeSSI™

New Sampling/Sensor Initiative (NeSSI™)
This effort started with an ad-hoc group of end-users and equipment manufacturers within CPAC who are looking to modularize and miniaturize process analyzer sample system components to simplify and standardize sample system design. The goals for NeSSI™ are to facilitate the acceptance and implementation of miniature, modular sample systems that has resulted in an ISA SP76 standard and to promote the concept of "smart" analytical systems by closely integrating flow, pressure and temperature with analytical sensors.
NeSSI™ has evolved to be useful for Process Optimization Studies, as well as for Process Control applications.

The following table shows significant milestones in the NeSSI™ program to date (organized in reverse chronological order) along with hyperlinks to related documents and presentations.

The CPAC Fall sponsor meeting was held November 5 - 8 at the University of Washington in Seattle. Jim Tatera put the spotlight on NeSSI™ on three occasions.

Mon Nov 8: Sponsor Symposium

The presentation (see CPACFall_M.ppt) updated the CPAC audience about the new analytical sensors and probes announced at ISA2001.

Mon Nov 8: NeSSI™ Update Session

An overview of the current status of NeSSI™ and a short overview of the Generation II spec was presented (see CPACFall_N.ppt)

Wed Nov10: NeSSI™ Focus Group

The Focus Group presentation (CPACFall_F.ppt). It is a "condensed" version of ISA/INTERMAC Tutorial. Several more people signed up for the A-, C- and X-teams respectively.

Nov. 2001

INTERMAC 2001

ISA (The Instrumentation, Systems, and Automation Society), JEMIMA (The Japan Electric Measuring Instruments Manufactures' Association) and SICE ( The Society of Instrument and Control Engineers) are presenting a joint conference on virtual and real technology for industrial measurement and control applications in the new millennium. The conference was held November 7 - 9, 2001 in Tokyo in conjunction with the 29th INTERMAC 2001, the largest exhibition for International Measurement and Control in Japan.

Rob Dubois presented the NeSSI™ tutorial- see the ISA2001 meeting above. CPAC's main objective for sponsoring this trip was to introduce the NeSSI™ concept to the Asian process analytical community. The presentation was well accepted albeit with lower attendance than Houston ISA. The outcome we believe will be greater involvement from Japan and the Far East in the coming months.
