For steam turbines, usually "relative vibration"
means "shaft relative [us. against bearing shell]
vibration" and "absolute vibration" concern bearing
pedestal vibration against free space, measured by seismic
transducer.
By combination of signals measured in one common axis by
shaft relative vibration transducer and bearing absolute
vibration transducer, "shaft absolute vibration" can be
calculated by electronic devices. In the past, "shaft
absolute vibration" was measured directly by sensors with
seismic system being in contact with rotating shaft surface.

Tell me the field calibration procedure step by step with diagram of pressure gauge, pressure switch, pressure transmitter, temperature switch, level switch, flow switch, flow transmitter.
