Progress on 7 elements of Gen II
• (1) Smart transducers• (2) Programmable heated substrate base• (3) Combi valve• (4) Multi-Drop IS serial bus• (5) temp. controlled microClimate
enclosure• (6) Sensor Actuator Manager (SAM)• (7) PDA – graphical user interface

(1) Progress: Transducers
• Flow– Thermal – cons: current
load, wiring complexity, robustness?
– DP with orifice – cons: pressure drop, size, cost?
– Rotameter switch/tx cons: cost and size
– need new technologies• Pressure & Temperature• Analytical (early stages)• Objective:
– single block, multi-drop– combine transmit and
local indication into one package

(2) Progress - Smart Heaters
• Approved for ATEX/CSA Zone 1
• First identified in 2003 now deployed in several locations
• Missing link is the connectivity to smart devices or stand-alone Courtesy of Intertec
11
Smart Heaters – the value
• Increase Reliability– early detection of heater failure (prevent freezing and
condensation/2-phase systems)– networking allows remote monitoring and setpoint change
• Technology Enabler– precision temp. controls supports the use of microanalytical
on a substrate – enables ramping and zoning– in combination with a precise flow meter allows use of
permeation calibration devices eliminating gas cylinders• Enhanced Capabilities
– higher temperature operation by controlling heater surface below the T-zone temp. - an alternative to air bath systems
• Cost Savings– conduction heat is more efficient than air heating– allows smaller package by compact hotplate design

(3) Combi-Valve Proposed
• Modulating & On-Off Valves – challenges
• size• power budget• cost• networking• technology to
make modulating is tough
– Proportional Valve is missing link

Simple On-Off Valve Driver
• Current solution– on/off solenoid
manifolds– needs “safe” area
for installation– various buses Courtesy of SMC
15
(4) Progress: Multi-Drop Intrinsically Safe Bus
• The inability to align to a standard has prevented us from moving ahead– component makers “in limbo”
• Good Features: plug and play, IS, low cost, low power, small, small range, std. connector
• Is this still the missing link?

Still a needfor convectionheating….

(6/7) SAM and the PDA
• Concentrates sensor/actuator signals – without this capability we will be
doomed to dumb systems– running signals from each sensor &
actuator to a facilities DCS system is not cost effective
– handheld PDA useful for local monitoring & simple control

Oh, the humanity…legacy wiring
Modular system with intrinsically safe discrete wiring – Dow Chemical (hydrogen service)

22
Enabler: Small flows allow wider use of catalytic sample disposal systems
• cost savings enabled by by-line analysis and low volume modular systems– eliminate vents
• environmental protection– a temperature sensor can
monitor catalyst depletion or heater failure and alarm that unit is failing
• performance enhancement– atmospheric reference
with no environmental impact – no analyzer backpressure issues

How do I achieve the WOW factor?
• Function Intensification• Reduce weight and space• Easily reconfigurable• Simplify the design and spec process
– one stop shopping, integration and check-out• Plug and Play communication• Minimize certification issues• Sensor/Actuator signal concentration/control loops• SMART (automated) – but configurable and easy (fun?)
to use for the analyzer technician (e.g. intuitive menu structure and graphics)

What do we need to do to fill the missing links?
