Scope

This part of GB/T 21487 gives details of how to obtain reproducible measurement
results in order to enable the monitoring and evaluation of shaft vibrations according to
the GB/T 11348 series. As such, it is concerned primarily with the measurement of shaft
vibrations for large machines (e.g. steam turbine generator sets, gas turbines, industrial
turbosets, hydraulic machines).
This part of GB/T 21487 is applicable to radial vibration measuring systems on shafts,
both for absolute and relative measurements. It covers the sensing device (i.e.
transducer), signal conditioning, attachment methods and calibration procedures.
