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.
