Answer / rajesh
Accelerometers are a piezo-electronic (crystal) device. A
pre- loaded crystal is charged with current and as the
crystal is compressed or de-compressed by vibration an
output proportional to g's (gravity) is provided. A "g" is
equal to 9.80 meters/second2 or one (1) standard earth
gravity.
Accelerometers are normally used for high-frequency bearing
cap vibration readings (Case/Bearing Cap Absolute on
machines using rolling element bearings. Usually the output
is integrated electronically to velocity (in/sec or
mm/sec). Other applications include monitoring Gears and
High Frequency Applications.
Eddy or Proximity Probes are a displacement device that
measure the relative motion between the probe mounting
location and the target (shaft). Output is directly
proportional to displacement and is usually measured in
mils (.001") or millimeters (mm).
Eddy Probes are used on machines with Journal (Sleeve) type
bearings. Where the measurement of motion between the
Bearing and Shaft is critical.

Answer / ch amir islam
There is no diffrence b/w these sensors thier method of
sensing is same depend upon the EDDY currunt
losses.ACCELEROMETER & PROXIMITY are diffrent way to
measure the vibration although they have same sensing
method as i told before.
