  1. New Sampling/Sensor Initiative“Electrifying” NeSSI -Wireless to the Rescue? Pittcon 2001 Meeting New Orleans, March 7, 2001

  2. V T P A Today: Brute Force Method Analyzer Controller • Power & Signal Delivered to Sensor from Controller Controller serve as the I/O Device Sampling System does not have any “Smarts” All Diagnostics in the Controller

  3. V T P A P V A T A • Local Sensor I/O Manager (like Opto22 devices or PLC) Local SAM Power Each sensor uses individual signal/power wires Requires Wiring Harness Useful for Remote Operation of Sampling System (such as NIR and RAMAN analyzers - would be a fiber-optic probe in this case) Legend: Pressure Sensor Temp Sensor Valve Analytical Sensor Alternative Brute Force Method ve Signal In/Outto AnalyzerController IA Controller (ASIC) SensorAnalyticalManagerSAM

  4. V T P A Improvement 1: Power Bus (Addressed in previous Session) Signal Wires Only SignalIn/Outto AC SensorAnalyticalManager(SAM) Shared Power Bus

  5. SRT SensorAnalyticalManager(SAM) V T P A SensorManager(I/OController) Improvement 2: Wireless Signal between SAM and Controller Analyzer Controller SRT = Sensor Receiver/Transmitter Type 2 Configuration

  6. SensorAnalyticalManager(SAM) V T P A SensorManager(I/OController) Improvement 3: Wireless Signal between SAM and Wireless Hub This configuration would be especially useful where Controller/Analyzer is remotely located from Sampling system (analyzer sensor in this case would typically be a fiber optic probe (e.g., RAMAN and NIR applications) Field Ethernet LAN WirelessHub Connected to Level 2 Ethernet Field LAN Type 3 Configuration

  7. SRT P A V T PowerModule Improvement 4: All Wireless Signal Analyzer Controller Type 4 Configuration

  8. A V T P Examples of Wireless Configurations Analyzer Server & Workstation Level 2 Ethernet Control System RAMAN, NIR etc. GP Area Fiber-OpticSensor. Field WH 1 on 1Type 4 1 on 1Type 3 2 on 1Type 2 1 on 1Type 2 1 on 2Type 2 WH = Wireless Hub
