This standard covers the minimum requirements for monitoring machinery shaft vibration@ shaft axial position@ and bearing temperatures. It outlines a standardized system for monitoring these items and covers requirements for hardware (sensor and instruments)@ installation@ calibration@ and arrangement.?This standard does not apply to accelerometer-based vibration monitoring systems@ which are covered by API Standard 678.NOTE: A bullet (?) at the beginning of a paragraph indicates that a decision by the owner is required. These decisions should be indicated on the data sheets (see Appendix A); otherwise they should be stated in the quotation request or in the order.
