Oct 18, 2012 ... Velocity sensors are used for low to medium frequency measurements (1 to 1000 Hz) and are useful for vibration monitoring and balancing ...
Some include converted vibration measurements between displacement, velocity , and acceleration for specific frequency ranges and severity classifications.
Vibration exposure direction is also important and is measured in defined directions. Vibration frequencies and duration of exposure are also determined.
Sep 5, 2011 ... Some use strain gauges, but many others use a capacitive effect or induced radio frequency mechanism to measure displacement directly.
