Single or dual process seal standards, which one's best?
A failure in process sealing between an electrical system and process fluids can be catastrophic if fluids migrate into the electrical system.
Over the years, well-defined standards have been established to address the requirements for process sealing between an electrical system and process fluids. Those most concerned about these standards are typically the owner/operators of process facilities and installers of electrical equipment and instrumentation. In this white paper you'll learn the strict series of tests that are required to gain single- or dual-seal marking, and why single seals, which must meet a higher performance level than dual seals, might be the better choice for your application.
