The vibration usually measured on the bearings of machine because bearings are often the place where damage occurs and where symptoms first develop.
Vibration measurements are usually taken at machine bearings, with accelerometers mounted at or near the bearings.
The number of vibrations in a wave at a given time is defined by its frequency. Frequency is the number of complete cycles or vibrations of a wave that occur in a unit of time, usually measured in hertz (Hz). So, at any given time, the number of vibrations in a wave is determined by its frequency.
Yes, that is correct. Frequency is the number of complete waves that pass a point in a given time, usually measured in Hertz (Hz). It represents the number of vibrations per second for a wave.
No, objects that vibrate quickly have a high frequency. Frequency refers to the number of vibrations or cycles of a wave that occur in a given time, usually measured in hertz. So, fast vibrations would have a high frequency.
Frequency is usually not measured in "levels" (though the sound pressure or volume is) Frequency is measured in Hz (Hertz) or vibrations per second. Sound pressure is measured in Decibels
Deep vacuum is usually measured in microns. This unit of measurement is commonly used in vacuum technology to indicate levels of pressure or vacuum.
Yes, property surveys typically show the direction of property lines as either bearings or azimuths. Bearings are measured in relation to the cardinal directions (north, south, east, west), while azimuths are measured clockwise from true north. Both provide important information about the orientation and boundaries of a property.

An accelerometer can be mounted on the surface of the machine which will measure the vibrations acceleration this is usually integrated to velocity for the purposes of analysis. Velocity is usually measured in mm/s (millimeters per second) or IPS (inches per second) in the US) while acceration in usually measured in G (9.8 mm/s/s). To convert between vibration acceleration, velocity and displacement you can use the following free tool from vibronurse the link is (http://www.vibronurse.com/cmcalculator.html). The alternative method is to use proximity probes (which uses an eddy current coil) these will normally be fitted to the machine by the original manufacturer.

Usually tapered roller bearings.

When you can hear them, usually.
lube the whell bearings once a year is usually all that is needed
response time is measured in Nanoseconds
Coins are usually measured in grams
They are measured in degrees, minutes and seconds
No, the hub is the outer housing that the bearing sits in. Usually bearings have to be pressed in and out of the hub.
