How does a vibration analyzer work?
Working Principle of Vibration Analyzers The method begins with the sensor or magnetic base device placed on the object whose vibration will be detected. The sensor will instantly give a voltage signal in response to the object’s vibration, which will be relayed over the cable into the vibration analyzers transmitter.
How do you monitor vibrations?
Vibration monitoring devices use accelerometers to measure changes in amplitude, frequency, and intensity of forces that damage rotating equipment. Studying vibration measurements allows teams to discover imbalance, looseness, misalignment, or bearing wear in equipment prior to failure.
What instrument measures vibration?
Vibration sensors, meters and analysers, usually called vibrometers, are portable devices which, thanks to various vibration detection methods – based on accelerometers or laser technology – measure the vibration level of a machine or its components.
What is CPM in vibration?
CYCLES PER MINUTE (CPM): In vibration analysis, cycles per minute refers to the number of vibratory cycles that occur in one minute of time. Cycles per minute is a quantity of frequency.
How many types of vibration are there?
A vibrating motion can be oscillating, reciprocating, or periodic. Vibration can also be either harmonic or random. Harmonic vibration occurs when a vibration’s frequency and magnitude are constant.
What are the types of sensors for vibration monitoring?
7 types of vibration sensors
- Strain Gauges. One type of vibration sensor is the strain gauge, which is a foil that’s applied directly to the surface of the machine being monitored.
- Laser displacement.
- Microphone sensors.
- Vibration Meters.
What is Viper II vibration analyzer?
The Viper II Vibration Analyzer is a versatile yet compact instrument that combines all of the diverse technologies required for high-end jet engine vibration analysis, transient balance, rotor track and balance, fan trim balance, propeller balance and acoustic analysis into one tool.
Why do I need a vibration analyzer?
It is convenient that the vibration analyzer you choose has the possibility to connect other types of sensors. There are machines for which simply the accelerometer is not the appropriate tool. Oil bearings is an example of the above because oil dampens the vibrations thus making its measurement with accelerometers less reliable.
What is an accelerometer in a vibration analysis?
Vibration Analyzers most commonly use Accelerometers due to their excellent frequency and amplitude range as well as the low noise they generate. In return, they convert acceleration into other parameters like velocity and displacements which are more frequently used in vibration analysis.
How is the frequency range of a vibration analyzer determined?
The frequency range of a vibration analyzer is determined by two factors: the highest sample rate of the analyzer and the maximum frequency that the accelerometer can measure. The Sample Rate is the amount of measurements that a system can perform within 1 second.
