BISOPE series 21- Spectrum setting method-Max frequency setting

--------------------------------------------------------------------------------------------------------------------------------------

In the spectrum, which is a graph for vibration analysis, “How many Hz should the maximum frequency be set?”, “What is the Fmax?”, “How much is the sample frequency?” If you are hearing these questions, you need to understand what the Max frequency is. Inquiries related to this can be divided into two types. One may ask what the term 'maximum frequency' itself is, and the other will mean how much to set the maximum frequency. Here we will try to answer your questions related to this.

 

The maximum analysis frequency (Max frequency) should be placed so that the frequency of interest is centered...

 

Fmax=2.56*Fs

 

maximum frequency; The maximum analysis frequency is expressed as ‘fmax’ and is t............

BISOPE series 9- Selection of appropriate sensor for condition monitoring measurement (focusing on vibration sensor)

-------------------------------------------------------------------------------------- -----------------------------------

For systems (online, offline) used for the purpose of efficiently performing maintenance (maintenance) by monitoring the state, reducing safety failures, and predicting the time of failure, a sensor that observes the state must be selected. There are many transducers (sensors) that convert these physical characteristics into electrical quantities, such as temperature sensors, pressure sensors, force sensors, flow sensors, position sensors, ultrasonic sensors, and current sensors. It is very important because it contains information, and it can be seen as the first gate that plays the role of the five senses (eyes, nose, mouth, touch, taste) that can check its stability or abnormal state. Therefore, if this sensor is not properly selected, the state cannot be represented and the alarm setting is also in error, so unnecessary and important values ​​cannot be trusted.

 

Considerations when selecting a vibration sensor for condition monitoring

The installation location and direction of the vibration sensor and the installation method are important, but first of all, the selection of the sensor is very important. It is basic to select a sensor according to the object to be monitored, but looking at other considerations, it can be summarized as follows.

 

1. It is not a high-speed, large-scale, critical facility, it is frequently disassembled and assembled, contains sufficient intermediate frequency, and it is convenient to select a magnet-attached acceleration sensor that measures the housing.
