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.
