eccentricity detector, speed, valve position, shell expansion, differential
expansion, rotor expansion, thrust position, vibration, and steam/metal
thermocouples. Also described is the
purpose of the instrument, the interpretation of data, likely causes of
operational problems and how to use the instrumentation for troubleshooting and
decision making. All related alarms and
