Thank God, ISA has wireless Internet in this conference room! My thumbs were beginning to die from doing the "Blackberry Prayer" too long. Sherman on NeSSI, continuing: Bob showed picures of actual products illustrating the principles of the S76 sample conditioning system...a modular system designed to maximuze efficiency and minimize costs, developed specifically for the process analytical instrumentation market, incorporating a single block and tubeset architechture for simplicity...it has become the perfect solution for most gaseous and many liquid sample conditioning systems. The idea is to provide a standard sampling substrate with easy maintenance, lower internal volumne and surface area, external space savings and on-board microprocessors and ASICs (at least in the future). Sherman went over the NeSSI roadmap and showed what will be coming. The current NeSSI specification is "mechanical: standard format control components." Next will be GenII: "Electrical/transducers/bus protocols, IS Ex). GenIII will provide for standardized microsystems including complete analytical devices and advanced control components. Although the S-76 standard is new, (2002), there are already substantial numbers of S-76 compliant components: -analyzers -controllers -filters -flow metres -pumps -regulators -switches, sensors and guauges -valves -developments SP76-based Analyzers: Spectrophotometer Cell (UV/NIR fiberoptic) Analyzers on a block: UV/VIS, NDIR, RI SP-76-based Controllers Gas Flow (mass basis, all 2-block format, except HoribaSTEC[1 block]) Bronkhorst Emerson/Brooks Honeywell(sensor) HoribaSTEC Porter Instrument Pressure Emerson/Brooks Flow Matrix Honeywell (sensor) Filters bypass and particulate cylindrical format membrane separator partiulate polishing TFE membrane Flowmeters Rotameters (armored and light duty) Emerson/Brooks makes both, and has 6-12 week or worse delivery Buehler makes light duty use common adaptors King (best delivery, light duty, 2 weeks) Kobold (both) Krohne (both Pumps ADI diaphragm pumps HNP Mikrosysteme GmbH positive displacement (gear pumps) Regulators Circor Tech Parker Swagelok These same three companies are the only vendors making NeSSI footprint substrates. Flow Switches ChemTec Delta M (the best, according to Sherman) Honeywell Malema FCI Moisture, Water switches Buehler Sensors, Temperature Honeywell Gauges Bourdon Valves NeSSI compliant ball, 2 and 3 way; check and relief valves are available The challenge is to reduce Life-cycle cost of sampling sywtems 35-70% Imagine: Integrating analyzers and sample systems Field mounted and self contained Smart incorporating diagnostics and control Open-architecture data systems Plug and play maintenance Standard designs for generic applications Enabling Technologies Modular sample system components developed in the semicon industry, and standardized by ANSI/ISA-76 Application Specific Integrated Circuits (ASICs) provide the smart components Open communication architectures: bus protocols provide data "transnipulation." Waltnote: Whoa! There it is again, folks, end users need open architectures! Field-mounted and self-contained --can work anywhere from the poles to the tropics No analyzer houses No long sample transport lines Minimum utilities' usage Reduced design time, build cost, life-cycle cost Smart with Diagnostics + Control --full system information available --remote modificatio of parameters --control of P, T F. Reduced Life-cycle costs
