NeSSI (An Analytical System)NeSSI (An Analytical System)...Will Look More Like Us!
Single Processor with Overall Control Sensor Analytical Manager or SAM
“the brain”
System will be Multifunctional Equal emphasis on all sensors
System will be Adaptable Predictive maintenance; self-
healing
Capable of Multivariate Analysis Use multitude of sensors for
analysisCourtesy of Kenneth Creasy

NeSSI: A Shared VisionR&D, End Users, Suppliers
An industrial platform for “lab on a chip” sensors
a suite of physical and chemical sensors and standard “off the shelf” software
at the pipe - “analytical transmitter”highly reliable - low maintenancelower LTCO and capital costsprofitability for suppliers

Summary
NeSSI/CPAC has articulated the VisionSubstrate & many components availableEncourage continued commercialization
of the VisionWe all need to collectively demonstrate
cost efficiencies & benefitsEnd Users must embrace and buy into
this revolutionary development
