The Application of Correlation Spectrum in Characteristics Of High Pressure Transducer

摘要

At present, it is a general method that is to obtain dynamic characteristic of high-pressure transducer using dynamic calibrating methods. There are limitations in characteristic of transducer obtained because of feature of the calibrating device. So the information in some frequency-band is not shown fully and it is affected by vibration mode of the device and stress wave created while calibrating process. The same transducer is separately calibrated on two different calibrating devices, and then the model of transducer is build by means of correlation spectrum using complementarily of two devices to diminish influences of devices.
