scope:

This Practice provides instructions for preparing a Process Analyzer Shelter Data Sheet.

The four general types of analyzer shelters that can be specified using PIP PCSPA003-D are as follows:

a. Type I - Field Mounted - An analyzer in an integral cabinet mounted on a freestanding support

b. Type II - Freely Ventilated - Typically a three-sided shelter

c. Type III - Climate Controlled - Shelter with a controlled interior that is necessary for proper operation of the analyzer system(s)

d. Type IV - Controlled for Electrical Area Classification Reduction - Shelter designed to accommodate and allow safe operation of analyzer system(s) that are not rated for the exterior electrical area classification of the shelter

Each analyzer shelter in a project shall have a separate PIP PCSPA003-D Data Sheet specifically tailored for its intended analyzer complement. This data sheet can be supplied directly to a shelter vendor for small applications or, with other supporting documentation, to companies specializing in analyzer system integration and packaging.
