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.
