what r all the type of viberation measurement measuring in
turbin? what's the output of viberation sensor?
Answer Posted / banerjeenandan
The answer No 1 given by Mr.Amit is absolutely correct. You
may need some more details.
The vibration sensors used in turbine, generator etc are all
same type i.e proximity type of sensors. The sensor are
mounted at the proximity of the Turbine and generator rotor.
From the sensors one coaxial cable runs to the proximiter,
which is mounted in a seperate JB nearby. From TSI Monitors,
this Vibration probes gets +24 Volts DC. The proximeter
gives a signal 0 to -22.4 Volts DC depending upon the
vibration measured by the sensor. Generally the diatance
between the probe tip and the rotor is maintained such that
it gives -10 Volts DC when the turbine is not running.
The sensor works on eddy current principle. As the rotor
vibration increases, the eddy current generation remains
contant, but the absorption of power in terms of eddy
current increaes. This loss of power is sensed by the
proximeter and DC voltage signal is transmitter to TSI
monitor for Measurement, Controlling & Indication purpose.
