Apical position；Consider the problems of that sensor can not effectively be connect with pipeline, sensor and pipeline enclosure are passed through into strong binder or frame
If outside support is fixed；The measuring point excessively high for some measurement difficulty yields measurement.It is summarized, traditional detection method
It has the disadvantage that
Firstly, not can guarantee being stably connected with for sensor and pipeline.Pipeline section top is placed directly in using by sensor
The mode of position, such sensor are contacted with the way of contact of pipeline for line.It is connect because line contact is that one kind is unstable in itself
Touching mode, and larger vibration of the pipeline in normal work, so that sensor can not almost be contacted with pipeline stabilization, Jin Erying
Ring the data acquisition being normally carried out.
Secondly, not can guarantee the accuracy and validity of test data.The mode of line contact occurs white when will lead to detection
Noise problem, and then interfere with effective acquisition of the sensor to data in measurement work；By the way of setting up outside support, pass
Sensor can acquire simultaneously the vibration data of external structure, cause the distortion of acquisition data；The biggish measuring point of detection difficulty is abandoned,
Will lead to testing result can not accurately reflect the actual vibration situation of structure.
Finally, being damaged to sensor larger.Using strong binder and set up outside support by the way of come guarantee sensor with
Effective contact of pipeline has biggish damage to sensor itself, and leads to the reduction of equipment measuring accuracy, duration of service
The problems such as reduction, testing cost increases.
