Vibration sensor based on 1)fixed pt sendor 2)variable sensor
fixed sensor -by manual scale fixed near to machine
valiable sensor-1)seismic transdusar 2)clectromechanical
tranducer 3)capacitive rtnasdusor 4)proximity type
5)photodiode type
proximity type -it is eddy current type .when we are giving
supply -24 v.sensor develop Rf field.in machine eddy current
develop ,due to current loss of power in Rf field so we get
in o/t less voltage depend on gap voltage
