This standard covers the minimum requirements for a machinery protection system measuring radial shaft vibration@ casing vibration@ shaft axial position@ shaft rotational speed@ piston rod drop@ phase reference@ overspeed@ 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 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 Appendix A); otherwise@ it should be stated in the quotation request or in the order.
