The purpose of this document is to convey conventional and widely accepted design practices used in industry for the engineering, design, and assembly of Process Analyzer Systems. Practitioners of this discipline are aware that each Process Analyzer System is a unique and customized entity. This document is intended as a prompt to an experienced analyzer systems engineer to ensure that a safe, reliable, and maintainable system is designed and engineered.
The other PIP analyzer documents in this series deal with proven means to specify, purchase, and install Process Analyzer Systems in an engineering and construction environment. These documents collectively provide a framework for obtaining pre-assembled analyzer systems from third-party vendors who specialize in fabricating complete Process Analyzer Systems. These specialists are frequently called Analyzer System Vendors (ASV).
Process Analyzer Systems are engineered, designed, and fabricated for one of the following:
Process measurement or monitoring Effluent measurement or monitoring Ambient atmospheric measurement or monitoring
A properly functioning system requires integration of multiple design tasks:
Selection of analytical technology Safety Sample extraction Sample transport Sample conditioning Sample return/disposal Utilities support Analyzer shelter Signal conversions and control system interfaces Status alarms Calibration facilities
A Process Analyzer System is not a commodity but is a custom-designed system to meet a specific requirement.
This Practice describes the engineering, design, and fabrication requirements for use by an analyzer systems engineer for the design and installation of process analyzer systems used for monitoring and control for the following measurements:
