Operating Characteristics of a Smart/ModularSample Handling System

Field Mountable Integrated or close coupled to the field analyzer, reduced time lag for sample transport

Simplified Improved serviceability and redundancy Modular Minimize the number of unique parts for

service and maintenance Smart Self diagnostics, alarms, automatic fault

correction (i.e. plugged filter) life cycletracking (i.e. valve life)Capable of advanced sample conditioning

Controlled Temp. More repeatable and accurate analysis

Rosemount Analytical is committedto developing and deploying theSmart/Modular SHS


CPAC/ RAI PAD/ 10/21/99/ 12

Technical Requirement of Smart/Modular SHS

n Components— Micro Electronic Flow Controller— Micro Flow Sensor(s)— Micro Electronic Pressure Reducer

n Electronics/Software— SHS should be controlled by the analyzer— Self diagnostics capability

n Material of Construction— Compatible with the process stream composition and temperature

required— Standardized/building block


CPAC/ RAI PAD/ 10/21/99/ 13

Challenges

n Components - Material tends to be 316 stainless. Analyzersuppliers must identify components of Hastelley C, Moneland other materials to provide full Hastelloy

n Temperature Limitations - Most commercially availablecomponents for Smart/Modular SHS have an upper range of65 c.

n Market Acceptance - At this time the nonrecurring costs for aSmart/Modular SHS is greater than a conventional SHS.Manufacturers need to reduce costs and assist customers inconsidering life cycle costs

Rosemount Analytical has an engineering groupactively involved in this activity


CPAC/ RAI PAD/ 10/21/99/ 14

Summary

n Simplified transmitter style analyzers have value to users— Improved control— Reduced nonrecurring costs— Reduced life cycle costs

n Smart and Modular Sample handling Systems are a logical“next step” to analyzer transmitters

n Most of the technology exists for Smart/Modular SHS

n Analytical companies, such as Rosemount, need to partnerwith end users for successful development
