Is that Speed Probe and Vibration Probe sensors are same,if yes what is the diff b/w them?..

normally we are measuring vibration signals are amplitude,
frequecy and phase.

for this we are using the same probe.

vibration is measured as peak to peak, a measure of the
total excursion of the rotor or machine casing in 'mils or
micrometers'.
Frequency is measure of how fast a body is vibrating and is
used to identify the source of vibrations. frequency is
expressed in shaft rotative speed.

for calibrating or checking probe or transmitter using for frequency (rotation / min )
1. adjust gap voltage at zero (-10V)at TK 3
2. put some small sticker on wobbulating part.
3. increase the speed of wobulator (TK3)
3. your out put is measured from multi meter at HZ range

thanks
