Before taking a vibration measurement, you need to attach a sensor that can ....
operating speed of the machine, the higher its frequencies of vibration will be, ...
Vibration measurement is complex because of its many components –
displacement, velocity, acceleration, and frequencies. Also, each of these
Displacement transducers are generally preferable if you need to measure low
frequency vibrations; accelerometers behave better at high frequencies.
Vibration exposure direction is also important and is measured in a well-defined
directions. Vibration frequencies and duration of exposure are also determined.
Feb 1, 1999 ... Some of the earliest "high-frequency" vibration measurements were made with
electrodynamic velocity sensors. These are a type of seismic ...
Sep 5, 2011 ... Some use strain gauges, but many others use a capacitive effect or induced radio
frequency mechanism to measure displacement directly.
