API STD 670-2014 PDF

Scope: General This standard covers the minimum requirements for a machinery protection system (MPS) measuring radial shaft vibration@ casing vibration@ shaft axial position@ shaft rotational speed@ piston rod drop@ phase reference@ overspeed@ surge detection@ and critical machinery temperatures (such as bearing metal and motor windings). It covers requirements for hardware (transducer and monitor systems)@ installation@ documentation@ and testing. NOTE A bullet ( ? ) at the beginning of a subsection or paragraph indicates that either a decision is required or further information is to be provided by the purchaser. This information should be indicated on the datasheets (see Annex A); otherwise@ it should be stated in the quotation request or in the order.
